Chương 9: Parametric equations, polar coordinates, and vector-valued functions
Giới thiệu
We are used to working with functions that take a variable (x) as an input and output a different variable (y). But there can be other functions, like functions that take two variables as inputs! Polar functions take an angle as an input and output a radius! Learn about these functions and how we apply the concepts of the derivative and the integral on them.
