Best Graphing Calculators for Students

By Kathleen Cantor, 02 Nov 2021

While many students use calculators to perform basic calculations, others use them for more complex graphing functions. Graphing calculators are used in some sciences and math classes. Students must know which type of graphing calculator will best suit their particular needs. 

What to Look for In a Graphing Calculator

A graphing calculator is an electronic device used to perform mathematical calculations. It consists of a computer chip, along with integrated circuitry that can be programmed for different applications. 

Students should consider the different functions each calculator offers before making a decision. The right calculator can help solve problems faster and more accurately, but the wrong one can be a huge distraction or frustration.

This device can provide answers to more complex problems than a simple scientific calculator. It is also useful when performing tasks in statistics, calculus, and many other math-related subjects. Students can use it to graph and analyze mathematical data and equations, which is a critical skill that they will need throughout their lives.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
