csc 150 corresponds to the point (-0.866, -0.5) on the unit circle. tan 5π/4 corresponds to the point (-0.707, -0.707) on the unit circle. cot 240 corresponds to the point (0.5, -0.866) on the unit circle. sin 315 corresponds to the point (-0.707, -0.707) on the unit circle.
sec(-5π/6): The angle -5π/6 radians corresponds to the point on the unit circle with coordinates (0.5, -0.866), so sec(-5π/6) is equal to 1/cos(-5π/6) which is equal to 1/cos(π/6) which is equal to 2/√3 or approximately 1.15.
can someone draw this idk how to do this unit circle
