The parser supports arithmetic, powers, parentheses, pi, e, sin, cos, tan, inverse trigonometry, square root, absolute value, logarithms, exponential, rounding, minimum and maximum. It never executes JavaScript.
Function samplingFor each x in the selected domain, evaluate y = f(x) with 81–321 evenly spaced samples.

The x-domain is sampled at evenly spaced points rather than drawn from a symbolic curve.
Trigonometric functions use radians.
Visible roots are estimated from sampled zeros and sign changes.

Each chart represents one semicolon-separated function.
The displayed minimum and maximum describe sampled finite values only.
A missing intercept does not prove that the mathematical function has no root.

Writing 2x instead of the supported explicit multiplication 2*x.
Using degrees directly in sin, cos or tan without converting to radians.
Graphing across a discontinuity and interpreting the connecting samples as a real curve.
