Sum and Difference Formulas (Identities) The sum and difference formulas in trigonometry are used to find the value of the trigonometric functions at specific angles where it is easier to express the angle as the sum or difference of unique angles (0°, 30°, 45°, 60°, 90°, and 180°). We memorize the values of trigonometric functions at 0°, 30°, 45°, 60°, 90°, and 180°.Learn what a cofunction is, how to calculate it, and how to use it in geometry and trigonometry.
