Here's a handsome grapher that works for implicit functions etc. and might have a better interface than Winplot, my old faithful. To copy to the clipboard, you'll need to download two Java files to your computer. I found it with keywords online graph implicit function.

The other day I found this site for integrals online. It led me to another site, Calc101, that has lots of capability for $25 a year. It gives step-by-step solutions: don't let it short-circuit your thinking.

I have also found a wonderful solution for getting math into MS Word documents: Aurora plugs in TeX bits so that one's math looks just right. There's enough help on the site that you can figure out all the TeX you'll want to know.
