WebCOMPOUND ANGLES FORMULAS. Now, compound angles are algebraic sum of two or more angles. Trigonometric functions do not satisfy the functional relations like. f (x + y) = f (x) + f (y) and f (kx) = kf (x), k is a real number. For example, cos (α + β) ≠ cosα + cosβ, sin2α ≠ 2sinα, tan3β ≠ 3tanβ. Thus we need to derive formulas for. WebUsing the distance formula and the cosine rule, we can derive the following identity for compound angles: cos(α −β) = cosαcosβ + sinαsinβ cos ( α − β) = cos α cos β + sin α sin β.
