Sun Position (polar coordinates) ... Altitude is the angular distance above the horizon (0 < h < 90°), and azimuth the angular distance, measured along the horizon, eastwards from the north point N in nautics (0 < alpha <360°), or westwards from the south point S (in astronomy).

Transformation of Horizontal to Equatorial Coordinates, ... One of the basic needs of astronomy, as well as other physical sciences, is to give ... A reference plane containing the origin is fixed, or equivalently the axis through the origin and perpendicular to it (typically, an "equatorial" plane and a "polar" axis);

When 3-dimensional polar coordinates overlap a cartesian (x,y,z) system, q is the angle between the line to the origin and the z-axis, while f is the angle (counter-clockwise when viewed from +z) between the projection of that line onto the (x,y) plane and the x-axis.

Polar coordinates have some very important uses. One of the most important is in the field of Astronomy. In your text, you learned about polar coordinates in two dimensions... But, we live in three dimensional space.
