# Surface Plotter in Spherical Coordinates

## How to use this applet

You have two angles in spherical coordinates; and which is the positive angle starting from x axis, on xy plane and is the positive angle starting from z axis.
This applet includes two angle options for both angle types. You can set the angles to create an interval which you would like to see the surface.
Additionally, spherical coordinates includes a distance called starting from origin. This distance depend on and . You will write a two variable function for using x and y for and respectively.
