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 #: 4

In rectangular coordinates x = 9.548, y = -27.57 and z = 52.65. What is the radial distance from the origin in spherical coordinates? r =
