"...TAKE CAPTIVE EVERY THOUGHT..." - 2 CORINTHIANS 10:5
Description: Recommended for most assignments. The most visually appealing and easiest to use graphing calculator on the internet; however, the axes are not scaled equally (producing accurate numerical values, but resulting in horizontally-stretched graphs).
Description: Highly recommended. Great all-around, equally-scaled graphing calculator that can graph any function (including inequalities); however, not as easy to use as the Holt graphing calculator.

Description: Very easy graphing calculator to use and manipulate; however, very limited in its functionality (no tables; only applicable for linear and quadratic equaions). *Website offers more visual scientific simulations.
Linear Regression Equation Calculators
Easy Interactive Regression Calculator
Description: Highly recommended. Same functionality as the "Easy Interactive Regression Calculator" while adding graphs and supporting quadratic and cubic functions.
