How to use it

Type a function of x, set the left and right edges of the view, and press Plot. The y-range auto-fits to what the function does.

Things to type

• sin(x) * x
• x^2 - 3
• 1/x (breaks are drawn as gaps, not lines)
• e^(-x^2) — the bell curve
• abs(sin(x))

What it can do

Any single-variable function · auto-scaling axes · clean handling of asymptotes and undefined regions.

What it can't do

One function at a time — it won't overlay two curves. The variable must be x (not t or y). It plots, it doesn't solve — to find where a curve hits zero, read it off the graph or use Algebra.
