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.]

  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

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

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 mix both types of math entry in your comment.
