6-89.

Solve for

*x*on the indicated domain. Homework Help ✎cos

*x*= 0, [0, 2*π*]2 sin

*x*+= 0, [0, 2 *π*]cos

*x*(2 sin*x*+) = 0, [0, 2 *π*]cos

*x*(2 sin*x*+) = 0

Use the Zero Product Property. Then combine parts (a) and (b).

Solve for all solutions.

Add a 2*πn* to each solution in [0,2*π*] where *n* is any integer.
