Question

Quizplus · Accepted Answer

The identity $\sin(\pi - \theta) = \sin \theta$ is based on the symmetry of the sine function with respect to the y-axis in the unit circle representation. This identity reflects the fact that the sine of an angle and the sine of its supplementary angle (in radians) are equal.
