How to Solve Equations Algebraically

How to Solve Equations AlgebraicallyMany students learn algebra at school, or they are taught it during the homework. There are few people who don't know algebra, and one of the most popular questions asked by them is how to solve equations. This question is common in physics and math classes too. The answer to this question is easy because algebra teaches you the principles of solving equations.One of the steps in solving an equation is to find the result. This can be done by the terms and variables, but sometimes this step is overlooked. The terms and variables are vital for solving equations. They describe the relationship between the quantities and the variables. The most common term in an equation is called a variable, while the most commonly used are the constant and the variable.The constant is the quantity that is constant, and it's value always remains the same. That is why this term is called the constant. The variable is used to express the values of the constants. This in cludes the speed of light, the time to a point in space, the square root of a number and the area of a square.Finding the result of an equation is not easy because all the relationships between the variables have already been discovered. One can choose to solve the equations with the different methods. It depends on the type of equation and the number of variables. Different methods will work for different types of equations. One should experiment on each of them to find out which method will work best for the problem.Solving an equation by hand is the most common method. You need to locate the points in the graph of the equation. Then you can mark the points using a black chalk and then use your pencil to fill in the rest of the blank places with the values of the variables. Some equations don't have enough points on the graph, so you can make some additions.Solving equations by hand may require some practice, so you can experiment with different solutions until you get it right. R emember that you need to be exact and don't simplify things. Simplifying things will lead to making mistakes, so keep your attention on the quantity. If you make a mistake, you can always try again.Since solving math problems is one of the major objectives of mathematics, it is better to master the technique than do anything else. For students who learn algebra at school, you should definitely give it a try. You can also use algebra online. This way you can find the answers anytime you want.

How to Solve Linear Equations

How to Solve Linear Equations If two linear mathematical expressions are connected and related by the sign of equality, an equation is formed. An equation satisfied for some particular value or values of the unknown quantity or quantities. The unknown quantity of an equation is called variable. For example: - a x + b = c x + d An equation containing one of the highest power of the unknown quantity is called a linear equation or first- degree equation. a x + b = 0, a 0 is an example of linear equation. How to solve a linear equation: - Question 1: - Solve the linear equation 2 x + 4 = 8 and find the value of x. Solution: -Step 1: - Try to keep all the variables on L.H.S. and constant on R.H.S. Constant 4 is there on L.H.S., so we can subtract 4 from both sides to remove 4 from L.H.S., and then we get 2 x = 8 4 2 x = 4 Step 2: - Try to free the coefficients from the variable. So we will divide both sides by 2 so that coefficient of 2 will be remove from both sides. 2 x / 2 = 4 / 2 x = 2 Therefore x = 2 Question 2: - 6 x 3 = 9, find x. Solution: -6 x 3 = 9 6 x = 9 + 3 6 x = 12 x = 12 / 6 x = 2

How To Play Bluegrass Guitar Common Fingerstyle Techniques

How To Play Bluegrass Guitar Common Fingerstyle Techniques Sign up successful Three-Finger Style Otherwise known as the Scruggs Style after banjo player Earl Scruggs who first popularized it, this fingerstyle employs a thumb pick, index finger pick, and middle finger pick to pluck individual strings on the guitar. The advantage over other picking styles is the speed at which experienced players can play arpeggios and string skipping runs without breaking rhythm. This gives the guitar a very percussive, lively sound that lends itself well to an ensemble setting. However, this isnt to say that players using this technique can only play single-note runs. Many experiment with combining this style with strumming via thumb pick or either finger pick. As always, you are free to play whatever you like! Three-finger style is versatile and popular but can be difficult for players with limited fingerstyle experience. When learning this style, try picking individual chord tones with a slow, consistent rhythm before speeding up as you are able. Using a metronome will greatly increase the effectiveness of these exercises because it will keep you honest! If you keep falling behind the beat, just turn it down and start slower. This kind of practice is the quickest way to become an amazing picker. Three-Finger Style Techniques Because many bluegrass fiddle tunes are in the key of C major, I have presented these exercises using C, F, and G chords to portray typical chord progressions. When you are learning how to play bluegrass guitar, it is wise to stick to a simple set of chords. It’s how you use them that matters. Three-String Runs The idea here is to use your thumb for the bass notes and your two fingers for the two high strings in each measure. If you pull it off, you can keep the rhythm strong with your thumb while filling out notes with your fingers. Try different chord tones to find the voicing that you like. Four-String Runs This exercise is almost identical the one above, except that the thumb is utilized not only for bass notes but also for a high string as well. Experienced bluegrass players learn to play in this style for the fastest of the fast songs. Make sure to start slow with that metronome! Two-Finger Style This variation of the Scruggs Style was favored by bluegrass guitar legend Lester Flatt. It omits the middle finger pick in favor of a simple thumb pick and index finger pick combination. Because of this simplicity, the two-finger style is easily adopted for purposes that resemble flat picking. The main idea is to use the thumb to pluck individual bass notes while strumming with the index finger. This is great for playing loud chords in a driving manner and is often used to carry the main harmony of the song. In addition, this style can be used to simulate bass lines in the absence of a bass player. But just like with Scruggs style, you are free to explore and find more ways to utilize this approach to playing bluegrass guitar. Here are some exercises I would recommend to become acquainted with the two-finger style. And don’t forget your metronome! Two-Finger Style Techniques Again, these figures are portrayed in C major for simplicity but you are not stuck here. Playing around with different chords will give you a better idea of what you and your guitar are capable of. Pluck-and-Strum This exercise is all about getting you acquainted with the capabilities of two-finger style. Specifically, it is about using your thumb to pluck the bass note of each chord before strumming two full chords with your index figure. Bluegrass ballads often call for this type of guitar arrangement. Fast Strum Now we’re getting to the fun part. Some bluegrass tunes are played at extremely fast tempos, and by speeding up the pluck-and-strum you just may manage to keep up. The key here is to play the chords almost as if you were flat picking with a normal guitar pick. The difference is that you can still use your thumb for the bass in two-finger style, but you will still most likely resort to strumming both up and down with your index finger. There’s no diagram for this one find a fast bluegrass song to play along to and try to keep up! (I usually use the song “Wait So Long” by Trampled By Turtles when I teach). Keep Practicing Some of these techniques may seem tricky at first, but don’t be discouraged. Practice at least ten minutes a day for two weeks and you’ll be seeing some serious improvement! No bluegrass guitarist ever became great overnight, and with these common fingerstyle techniques you now have a roadmap for how to get there.

Singing Tips How to Sing Into a Microphone

Singing Tips How to Sing Into a Microphone Sign up successful Step 2: Learn How to “Play” the Microphone The best way to approach working with a microphone is to think of it as an extension of your voice. Rather than “projecting” your voice like you would in an acoustic setting, let the microphone do the work and focus on your delivery, pitch, and emotions. Here are some key singing tips to keep in mind when developing your microphone technique: 1. Practice your angles.  Every microphone has a “sweet spot” where it is most effective. If you sing into the microphone at the improper angle you may lose important tonal characteristics from your performance. Always sing into the center of the microphone, never the side or top. It takes some practice, but once you understand your microphone, it will pay off in a fuller, richer sound! 2. Hold the microphone properly for best results.  Always hold the microphone by the shaft. While it may look cool to hold the microphone by the head, it can muffle your sound, or worse, create ear-shattering feedback from the PA. 3. Proximity effect is your friend!  Most microphones used for singing live are subject to something called proximity effect. This means that the distance you sing from the microphone affects the timbre of your voice. Singing closer to the mic, for example, enhances the lower frequencies. This can be a pleasant sound, but if you find your vocals too boomy, try moving an inch or two back from the microphone. 4. Experiment with different vocal effects. Working with a microphone allows you to use various effects to enhance your voice. Try singing and adjusting the airflow through your nose, opening your throat to provide more resonance, and working on your glottal attack, enunciation, and vibrato. By working on these different techniques in front of the microphone, you can develop the muscle memory needed for performance. Treat using a microphone like any other vocal techniquepractice it often! As a vocalist, you have to practice many techniques in order to use your instrument well. If you study with a private teacher, he or she will be able to help you, as well. If you are ever planning on performing in front of an audience, practicing with a microphone can make the experience less stressful, more enjoyable, and will go a long way toward your personal and professional growth as an artist!

How to Decide Between AP and IB Classes

How to Decide Between AP and IB Classes For high-achieving high school students seeking a challenge, there are two abbreviations to become familiar with: AP and IB. AP, or Advanced Placement, classes help prepare high school students for college by providing the opportunity to take one or more college-level courses and earn college credit. IB, or International Baccalaureate, classes are part of a system where high school students can earn an internationally recognized diploma by following a specific course program. Both AP and IB courses offer students a challenging academic experience and the opportunity to earn college credit. Students can choose between AP and IB classes by understanding the goals of each program, researching program availability, and examining the time commitment of each. If youre looking to challenge yourself academically this fall, keep reading to discover how to decide between AP and IB classes. AP vs. IB classes: understand the goals of each program Both AP and IB courses set out to give students an advantage when applying to colleges. That being said, its important to know the specific goals of each program, in an effort to choose the right one for you. The main goal of an AP course is to educate students about very specific content in subjects ranging from biology to U.S. history. Students interested in AP classes should note the following: AP students are tested on what they have learned via a multi-hour exam at the end of the course. The exam includes several question formats, but is primarily multiple-choice. The score students earn, on a scale of one to five, dictates whether or not they receive college credit. Like an AP class, IB courses discuss specific subjects. The International Baccalaureate Organization presents a curriculum that primarily incorporates exams, papers, and projects. Students interested in an IB class should note the following: Tests may be scored by external assessors, who assign a score between one and seven. While IB courses require exams, the focus is on question formats that are not multiple-choice. [RELATED: What High School Students Should Know About IB Courses] AP vs. IB classes: research which courses are available to you AP courses are more widely available in American schools than IB classes. However, there are many American high schools that offer IB courses as well. Students who dont have access to AP courses in school can also take them online, which makes them much more readily available. If youre interested in learning more about whats offered at your school or how to take AP classes online, speak to your guidance counselor. [RELATED: The Ultimate Study Plan for AP Courses] AP vs. IB classes: examine the required time commitments Students can take one or more AP classes of their choosing throughout their high school career, with each course lasting the length of the school year. IB students, alternatively, are required to take a somewhat set program of advanced courses in order to receive a diploma for the program. Certain high schools also offer standalone IB classes. If your schedule is packed with extracurricular activities or personal obligations, it may be wise to take fewer advanced courses so you can devote the appropriate time to each. AP vs. IB classes: note the cost of each program Enrolling in an IB diploma program is more expensive than taking an AP course or courses. Theres a $172 registration fee to enroll in an IB program, plus a $119 fee per exam, according to International Baccalaureate. AP classes, on the other hand, are free to enroll in and only cost $94 per exam, according to the College Board. Students are only required to take the exam if they want potential college credit. The cost of the two programs can be a large factor when deciding between AP and IB classes. It can be helpful to talk to your parents to see which option is the best fit for you and your family. Note that there are fee waivers available for both AP and IB exams. When in doubt, meet with your guidance counselor to gather more insights on choosing between AP and IB classes.

Morning Mayhem Try These 7 Steps

Morning Mayhem Try These 7 Steps Mornings can be hard for kids with ADHD and their parents. Having ADHD can make it hard to wake up in the morning, keep track of time, and get things done independently. So, its very common for families of kids with ADHD to feel rushed, stressed, and disorganized before the school and workdays even begin. Starting your day off this way is hard on you and your child. A few simple changes can make mornings better. Good mornings start with a good nights sleep. According to the National Sleep Foundation, children between the ages of 6-13 require 9 to 11 hours of sleep, and teens between the ages of 14-17 need 8 to 10 hours of sleep. Wake your child up at the same time every day. This routine will help regulate their circadian rhythm and make it easier for them to get out of bed in the morning. Create a checklist. Together with your child, make a list of the things they need to do each morning. Try to keep the list limited to no more than 7 items. For example: Wake up with only 1 reminder from mom by 7:20 Brush my teeth Wash my face Brush my hair Get dressed Eat breakfast and finish my 7:50 Post the checklist in a spot where your child can see it every morning. Make it look fun and let your child decorate it -- it helps your child feel like they own the routine too. When your child finishes all the steps, provide a lot of praise. Make sure your praise is truthful, specific and positive. Great job brushing your teeth without needing a reminder. or 7:45am and done? High five! Way to go! Consider providing your child with a reward as an extra incentive to finish their morning routine independently and on time. Rewards can be simple, but they should be immediate. Things like picking a special snack for lunch, choosing the radio station in the car on the way to school, getting a special hair style, or getting 10 minutes of screen time. When your child is first learning their new routine, you may need to provide supervision and an occasional reminder. So, try to get yourself up and ready a bit early on the first few days of the new routine. This way youll be able to give your child your full attention when they need it. ABOUT DR.
