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..?

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.

A good exercise comparing exponential functions.
