1-187.

Solve the following equations for all values of *x* in the domain [0, 2*π*). Use exact values. Homework Help ✎

sin(2

*x*) = sin(*x*)sin(2

*x*) = 2sin(*x*)cos(*x*). Substitute and solve for*x*.There will be four solutions.

sin(

*x*+*π*) + cos= 1 There is no solution to this problem.

cot(

*x*) – tan(*x*) = 2There will be four solutions.
