FAQ

Which functions and operators are supported?

Use +, -, *, /, powers and parentheses, plus sin, cos, tan, sqrt, abs, exp, ln, log and the pi and e constants.

Can I enter y=x^2 directly?

Yes. The y= and f(x)= prefixes are optional, and implicit multiplication such as 2x or 2(x+1) is supported.

How does the animation work?

Each plot traces the curve from its leftmost sample. Choose Replay animation at any time to start again.

Is my expression uploaded?

No. Parsing, calculation, sampling and drawing all run locally in your browser.
