Graphing Calculator
Seeing a function drawn makes its behaviour obvious. Type any expression — like x^2, sin(x) or 2*x+3 — and watch the graph appear instantly, with pan and zoom to explore every part of the curve.
Supported: + - * / ^ (power), sin cos tan, sqrt, abs, log (ln), exp, pi, e. Use a semicolon for 2 functions:
x^2; 2*x+1How to use
- Write a function, for example
sin(x)orx^3 - 2*x. - Set the X range and press "Draw Graph".
- Drag with the mouse to pan, and use the buttons to zoom.
Tips
- Start with the default X range, then zoom into interesting regions instead of guessing a range first.
- Watch for breaks in the curve — functions like 1/x are undefined at x = 0 and the gap is meaningful.
- Compare two functions by graphing them together; intersections show where expressions are equal.
- If the graph looks flat, widen or shift the range — you may be looking at a boring slice of an interesting curve.
