Use x, pi, e, +, −, *, /, %, powers (^), parentheses and functions such as sin(x), cos(x), sqrt(x), log(x), ln(x) and abs(x). Trigonometric plots use radians.
How this tool works
Each expression is parsed and sampled locally across the selected x-range. The SVG graph breaks at undefined points and large discontinuities rather than connecting them with misleading lines.
