There are many common mathematical curve functions. The following are some common mathematical curve functions: power function, exponential function, logarithmic function, trigonometric function, inverse trigonometric function and so on. In addition, there are some common curves, such as cubic parabola, semi-cubic parabola, probability curve, tongue line, rattan line, Cartesian leaf line, star line (a kind of hypocycloid), cycloid, heart line (a kind of epicycloid), archimedean spiral, logarithmic spiral and hyperbolic spiral.
