So you've nearly survived High School and are about to take the SAT. All of your time studying is finally coming to a head. But now you are probably wondering, overthinking, and stressing about what calculators are allowed on the SAT. WHICH CALCULATORS ARE ALLOWED ON THE SAT? Image Source: Pixabay Luckily, the answer to the question of what calculators are allowed on the SAT is quite simple. Most graphing calculators, including the bulk of Texas Instrument calculators, all scientific calculators, and all four-function calculators will be permitted on the SAT. The … [Read more...]

## Best 3D Graphing Calculator With Multiple Functions

Math is such a daunting subject for many because it can be so abstract. One way to ground the concepts of math is to graph the functions you study. In beginning math courses, these are typically very basic functions with one variable, like straight lines and parabolas. As your math courses become more advanced, the functions you study also become more advanced. Eventually, math students study functions with multiple variables. These kinds of functions are extremely insightful and can emulate critical parts of the natural world. However, in order to study them, new … [Read more...]

## The Best Calculator for SAT Success: Picking Your Graphing Calculator

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 … [Read more...]

## How To Use a Graphing Calculator

Like it or not, learning how to use a graphing calculator is a vital part of your education. Even if you know for a fact that math is not an essential aspect of your future career, learning a wide variety of subjects will help develop you into a critical thinker. You may be surprised by how many fields of study rely on mathematics for their framework. For example, what would sociology be without statistics? It would probably just be philosophy. Even creative skills, such as art effectively utilize graphs. In any case, knowing how to use a graphing calculator actually … [Read more...]

## Delta S and How to Calculate it in Chemistry

If you've ever taken a chemistry class, you know that it's really more math than anything else. There are so many equations that you need to know in order to understand chemical processes. One of these involves how to calculate Delta S. Delta S has to do with entropy, which is just a scientific word for disorder. It may seem a little strange that someone can measure or calculate disorder, but they actually can. In order to calculate it, however, they need to know a few other variables. You may or may not be a science buff, but either way, you'll almost certainly find … [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: Desmos On the other hand, if you have 10 + 20 + 40 + 80 … the sum of the series only … [Read more...]

## TI-82 Guide: Basics, Special Functions, And 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...]
