Systems of Equations Resources

This is a neat 3D function grapher and allows you to see functions in 3D space. This is helpful in visualizing an equation that has an x, y, and z variable.

Graph lines, inequalities, systems of equations, this calculator can do it all.

Baller! Play some hoops with this Systems of Equations game modeled after a basketball game. This game can take 2 or 4 players.

Do you want to double check your matrix calculations? Here's a nice online matrix calculator that has everything including transpose and inverse matrix operations.

Here's another matrix calculator if you don't have a calculator that can do matrix operations. This one is very user-friendly!

This coolio toolio can do elementary row operations on a matrix! It was developed at Hofstra University and allows you to type in a matrix, multiply rows by a number and add to different rows. It will even reduce the matrix and swap rows.

This is the gold standard for calculating things and crunching numbers. Wolfram Alpha can even take an algebraic fraction and decompose it into partial fractions.

The folks at hotmath explain elementary row operations. This will be helpful if you need some more examples when solving systems of equations with matrices.

Here's a step by step guide on how to decompose partial fractions – for dummies. Yet another link to help develop your knowledge of this complicated topic.

Paul has some good notes here about solving systems of non-linear equations. He delves into some advanced problems involving complex roots.
