There's the hard way and the easy way. Personally I like the easy way best:

From the complementary angle formulae: .

**Case 1:**where n is an integer.

Solve for x and substitute appropriate values of n to get all values of x satisfying the given domain.

**Case 2:**where n is an integer.

Solve for x and substitute appropriate values of n to get all values of x satisfying the given domain. - September 6th 2008, 02:01 AMose90
