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