Solve for

*x*on the indicated domain. Begin by solving for the function. Recall that if no domain is indicated, the domain is all real numbers. Remember to use either a unit circle or wave graph as a visual reminder. Homework Help ✎2 sin

*x*− 1 = 02 + 2 cos

*x*= 0− 2 sin *x*= 0cos

*x*+ 3.8 = 0, [0, 2*π*]
