Graphing calculators are used in many disciplines, from pre-calculus, calculus and statistics, to physics and engineering.

If you are looking for a one-stop graphing shop, visit WebGraphing.com. This website is 100% dedicated to helping you graph whatever your heart may desire.
Bottom line: a graphing heaven.

An awesome free graphing calculator is available from Desmos.com. Do you want to scream the minute you even think about online graphing apps? If so, this one is for you! It is a complete graphing calculator that is very straightforward and good looking. It is not confusing like some of the other graphing calculators out there as it resembles an actual calculator with buttons and all. You can register for free to save and share your graphs, which is great, since most online students are required to submit virtual graphs nowadays, and most online calculators don’t give you this option.
Bottom line: a simple graphing solution for those of you who love buttons.

Equation “Graphers”

These handy flash applications will graph the equations for you. Pay attention to the instructions, as these programs may produce erroneous graphs if your inputs aren’t “to the T.”

There is a free equation “grapher” available from FreeMathHelp.com.

Bottom line: a basic online app to help you graph equations, minus all of the other junk.

Equation Solvers

Equation solvers are applications that help simplify and solve equations and systems of equations.

A great equation solver is available from WolframAlpha.com. It solves linear equations and systems of equations; equations with parameters; trigonometric equations and polynomial equations. Equations aside, Wolfram Alpha is a great resource for all disciplines, offering various calculators for every imaginable subject. The company itself calls its website “The computational knowledge engine” (and they are not exaggerating by the way).
Bottom line: a comprehensive equation solving solution.

A basic equation solver is available from NumberEmpire.com. Similar to Wolfram Alpha, it generates solutions to equations and systems of equations. It may be a better option for our ADD-prone friends, as it offers its infinite math wisdom on a white background with less distractions and shows some of the more important steps leading up to the solution.
Bottom line: basic, distraction-free equation solver.
