2. Consider the function f(x,y) = √x² - y². Convert the function to the indicated coordinate system or format. a. Write f in spherical coordinates. b. Write f in cylindrical coordinates. C. Write f in parametric surface form, ŕ(u,v).

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
