Editing Spherical coordinate system (section)

=== Plotting ===
To plot any dot from its spherical coordinates {{math|(''r'', ''θ'', ''φ'')}}, where {{mvar|θ}} is inclination, the user would: move {{mvar|r}} units from the origin in the zenith reference direction (z-axis); then rotate by the amount of the azimuth angle ({{mvar|φ}}) about the origin  ''from'' the designated ''azimuth reference'' direction, (i.e., either the x- or y-axis, see [[#Definition|Definition]], above); and then rotate ''from'' the z-axis by the amount of the {{mvar|θ}} angle.
