what is the formula of trigonometric. Trigonometric Identities are formulas that involve Trigonometric functions. A formula for computing the trigonometric identities for the one-third angle exists but it requires finding the zeroes of the cubic equation 4x 3 3x d 0 where x is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
