Maths Grapher

Plot equations with x and y.

Draw implicit curves like x^2 + y^2 = 1, layered functions like y = sin(x), and extra forms like parametric and polar curves. Pan by dragging the graph and zoom with + and -.

Supported math

Variables: x, y, t, theta. Operators: +, -, *, /, ^, parentheses. Functions and constants: sin, cos, tan, asin, acos, atan, sqrt, log, ln, exp, abs, floor, ceil, round, pi, e. For implicit graphs, write left = right, write one side to mean = 0, or use inequalities like 0 <= x^2 + y^2 <= 1 to fill the region and draw its boundary.

Examples to try

x^2 + y^2 = 1

(x^2 + y^2 - 1)^3 = x^2 * y^3

tan(y) = sin(x)

x + y = sin(y * cos(x))

x = sin(3 * t), y = sin(4 * t)

r = 2 * sin(4 * theta)
