Graphing linear equations
I found a pretty good applet that allows you to graph and view changes in equations/function:
I found some drawbacks with this program.
You cannot copy/cut and paste former expressions from the application itself. I tried typing the the expressions in a word document and then pasting them, and this didn’t work either.
Also, you can’t place lines from different functions on the same graph to compare.
I’m sure there are other graphing tools out there that do this. I just have to find them.
