If csc theta = -5/3 and theta has its terminal side in Quadrant III, find the exact value of tan 2theta.??
Draw a right triangle. Label the Right Angle. Label one of the acute angles \(\theta\). Properly label two sides of the triangle according to the cosecant information given. Let's see what you get.
tan2x = 2tanx/ (1-tan^2x)
