6-50.

Many times when solving trigonometric equations, the solutions are not convenient values on the unit circle where the answers are exact. For example, and the exact solution between

Solve

for and give a decimal approximation.Is this the only solution between

and ? Use what you know about the symmetry of the sine function and the unit circle to determine the other solution between and . Use the unit circle and symmetry.

How can you write this?
