Some Hints & Solutions

Coordinate Systems: 3D

(Note: there are two spherical coordinate system conventions. The one used here is that the angle is on the plane z=0, measured clockwise from the x-axis. The angle is the angle relative to the z-axis.)

Variant #: 2

In cartesian coordinates x = -40.33, y = -31.73 and z = 14.91. What is the radial distance from the origin in spherical coordinates? r =
