A cofunction in trigonometry is a connection between two trigonometric functions that are connected by a complementary angle. In another way say that the cofunction of an angle is the trigonometric function of its complement. The cofunction identities make the connection between trigonometric functions and their "co" counterparts like sine and cosine. Graphically, all of the cofunctions are reflections and horizontal shifts of each other. cos(π 2 − θ) = sinθ. cos ( π 2 − θ) = sin θ. sin(π 2 − θ) = cosθ.May 9, 2022 · Use the sum and difference identities to evaluate the difference of the angles and show that part a equals part b. \ (\sin (45°−30°)\) \ (\sin (135°−120°)\) Solution.
