WebbTrigonometric identities. An equation involving trigonometric ratios of an angle is said to be trigonometric idnetity, if it is true for all values of the angles involved. Some of the key trigonometric identities used in this chapter are as follows: sin 2 A + cos 2 A = 1; sec 2 A =1 + tan 2 A for 0° ≤ A ≤ 90° cosec 2 A = 1 + cot 2 A for 0 ... WebbThere are several options a student can use when proving a trigonometric identity. Option One: Often one of the steps for proving identities is to change each term into their sine and cosine equivalents: Example 1: Prove the identity: Solution: Reducing each side separately. It might be helpful to put a line down, through the equals sign.
