**MathMate**, Tuesday, October 13, 2009 at 7:34amCoterminal angles for an angle α are angles of the form α±2kπ where k is different from zero.

For example, some coterminal angles of π/2 are:

π/2 - 4π = -(7/2)π

π/2 - 2π = -(3/2)π

π/2 + 2π = (3/2)π

π/2 + 4π = (7/2)π

π/2 + 2π = (5/2)π

π/2 + 4π = (9/2)π
