Tangent Addition Formula TUTOR TTD
Angle addition formulas express trigonometric functions of sums of angles alpha+/-beta in terms of functions of alpha and beta. The fundamental formulas of angle addition in trigonometry are given by sin (alpha+beta) = sinalphacosbeta+sinbetacosalpha (1) sin (alpha-beta) = sinalphacosbeta-sinbetacosalpha (2) cos (alpha+beta) = cosalphacosbeta.

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 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.
Solution. By recognizing the left side of the equation as the result of the difference of angles identity for cosine, we can simplify the equation. sin(x)sin(2x) + cos(x)cos(2x) = √3 2 Apply the difference of angles identity. cos(x − 2x) = √3 2. cos( − x) = √3 2 Use the negative angle identity. cos(x) = √3 2.
