Polar Curve Calculator

Enter r as a function of t (the angle in radians) to plot a polar curve.

Curves to try

• 1+sin(t): a cardioid
• 2*cos(3*t): a three-petal rose
• t/3: an Archimedean spiral (set t max to 18)

How to type functions

Use x as the variable, ^ for powers, and sin, cos, tan, asin, acos, atan, sqrt, abs, exp, ln (natural log), log (base 10), pow, floor, ceil, round, min, max, pi and e. Use brackets for clarity, for example (-x)^2.
