Question

Use inverse functions where necessary to solve the equation. (Use n as an integer constant. Enter your answers as a comma-separated list.)

2 cos²(x) + 13 sin(x) = 8

Answer 1

The answer is pi/6 and 5pi/6 and 2n pi + these 2 values but the editor will not allow me to show the work.

I will notify Wyzant of this problem, but you should complain to Wyzant as well. Thank you.
