Webb17 dec. 2024 · Reciprocal Identity As you recall, there are six trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. The first three are the most commonly used, while the latter three are the inverses of the first three. By this definition alone, these are called the reciprocal identities. Webbcos(22.6°) = sin(67.5)° Therefore, the value of cosine B is equal to sine A which is the cofunction and complement of B. The process remains the same whether you are in degree mode or radian mode. Let's see how this can be applied. Use the cofunction identities to evaluate the expression without a calculator! sin 2 (23°) + sin 2 (67°)
