Choosing the best calculator for SAT testing could have an immeasurable impact on your life. Where you go to college (and if you choose to go at all) could determine pretty much every career choice you make throughout your life.Of course, the college admission process doesn't start when you fill out your application. The major you pick, the friends you make, and the school you attend all ride on the back of your SAT score.With that in mind, why risk letting something as seemingly minor as the calculator you use affect you? The college admission process is hard enough, … [Read more...]

## Calculators 101: How To Find The Best Calculator For Every Budget

Most high school students come to math class equipped with the best calculator money can buy. Armed with their trusty calculator, no equation is too large or too complex to solve.Enlightened by their teachers who say they will use all these math equations into adulthood, they study hard and soak up the information like sponges.But unless you're a math professor, an engineer, or something equally as math-dependant, you won't need to use your scientific calculator to solve quadratic functions or parabola problems.The average Joe's real-life scenario mostly require … [Read more...]

## Convergence Calculator; How To Calculate Geometric Series?

Even in a second-semester calculus class, determining the sum of an infinite series is beyond the scope of what you'll typically be asked to do.One exception to this, however, is when you're working with an infinite geometric series, and you need to determine whether its sum is finite or infinite.For example, if you have 1/4 + 1/8 + 1/16 … the sum of this infinite series will ultimately approach – that is, converge upon – 1/2, and that makes its sum finite.Image source: DesmosOn the other hand, if you have 10 + 20 + 40 + 80 … the sum of the series only continues to … [Read more...]

## Trapezoidal Rule Calculator: Applications, GeoGebra, And More

Imagine you have an x-y graph with a plotted line running from left to right. In addition to marking these specific data points, you may need to calculate the area of the region under the line. While this is easy enough to do with a straight line, a curving, irregular line is more problematic. This is where the trapezoidal rule comes into play.The trapezoidal rule creates a series of side-by-side, left-to-right trapezoids under the curve. All the individual trapezoid areas are then added together to calculate the total area under the x-y points making up the curving … [Read more...]

## SAT Calculator Hacks: Trigonometric Values, Graphing, And More

The SATs (Scholastic Aptitude Tests) are among the more nerve-wracking of high-school experiences, as many colleges use the SATs as a primary factor when determining student admission. Scholarships and more can rest in the balance of an SAT score, leading to crippling test anxiety among even the most dedicated students.Compounding matters is the fact that the test is timed, which can further increase a student’s anxiety. Even if a student is very well-prepared, knowing that a proctor is sitting with a running stopwatch can place an additional strain on a student’s … [Read more...]

## Using A Tangent Calculator With Degrees And Minutes

The word “trigonometry” might strike a note of dread with many people as they recall struggling through high school math classes, but the truth is that trigonometry comes in handy in a wide range of science and math applications.Having a calculator for advanced math and trigonometry work is great, but it can’t help you out unless you understand what you’re doing and know how to use it. We’re going to talk a little about how to use a tangent calculator with degrees and minutes, and some of the principles and theory behind these higher-math functions.What Is a Tangent? … [Read more...]

## Your Ultimate Guide To TI 84 Calculator For Higher Math Courses

If there’s one company that can take credit for developing the hand-held calculator, it’s Texas Instruments.
