Interactive factoring help for trinomials and difference of squares. Also equations and graphing

An online graphing calculator with great visual presentation. Nice thick lines for projection. Implicit graphing. Easy tracing. Mulitple functions (and relations!) graphed at once. It looks like this tool is under ongoing development, and a committment to remain free. This one is a keeper.

I found it difficult to enter the equations, the keyboard keeps disappearing and keeps blocking the equation. Any hints..?

This Add-In for MS Word and MS One Note integrates many features of Microsoft Mathematics with microsoft's equation editor (Word 2007 and 2010). Most importatnly it produces attractive graphs which would be great for test preparation, but while it has several controls for window, scale, etc., I have not found any for line thickness or colour. Work around this by converting graphs to greyscale, increasing contrast, and decreasing brightness via Picture Tools > Format after inserting a graph.

Microsoft Mathematics is a free graphing calculator and CAS for windows. It has an equation solver that shows a step by step process, and in my quick test it also gives restrictions on solutions. Will integrate and differentiate expressions, work with matricies, and more.

An alternative way to think of y=mx+b and graphical development.
