# 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.

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.

now i feel as though I want to learn maths again.

2. Shivam Chaturvedi says:

Really Great Piece of Software. I'm going back to school!

3. martha augustine says:

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

4. Murray says:

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.

5. Ranjan Biswas says:

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

6. Murray says:

You're welcome, Ranjan. KIS looks like an interesting school in a lovely location!

Hi,
There are also other sites like GraphSketch.
I created one site like that to help my classmates get a better understanding of how the graph of a function looks. Now it is online at graphmaker.tk
I hope you guys test and like it. Here's the link:

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
a^2 = sqrt(b^2 + c^2)
(See more on ASCIIMath syntax); or
2. Use simple LaTeX in the following format. Surround your math with $$ and $$.
$$\int g dx = \sqrt{\frac{a}{b}}$$
(This is standard simple LaTeX.)

NOTE: You can't mix both types of math entry in your comment.
