# GraphSketch.com - free online math grapher

By Murray Bourne, 25 Mar 2009

Here's a great service for math students and teachers.

GraphSketch will plot a range of functions including polynomial, trigonometric and exponential ones.

You can download the resulting plot as a PNG image and use it in your notes.

I like the anti-aliased (smooth) edges of the resulting curves — I find it unsatisfactory that most graphers give you chunky, pixelated ones.

Here's an example (it's *f*(*x*) = tan *x* and *g*(*x*) = arctan *x* plotted on the one set of axes.

This is a well-executed, free application. The link again: GraphSketch.

[Thanks to JackieB for alerting me to GraphSketch.]

This is great. I use graphmatica which I find very useful.

Thanks, Martha. I remember I tried out Graphmatica some years ago. It's quite versatile and nice that it handles relations (eg circles) as well as functions.

I don't know how to thank you. Thanks a lot. It has made my teaching dynamic
