Double Angle Tan Formula

Double Angle Tan Formula. These identities are summarized in the first two rows of the following table, which also includes sum and difference identities for the other trigonometric functions. ( 2) tan 2 x = 2 tan.

Summary of trigonometric identities from mathcs.clarku.edu

It covers using double angle formulae of sin, cos, and tan to find exact values of trigonometric ratios or verify identities. The trigonometric double angle formulas give a relationship between the basic trigonometric functions applied to twice an angle in terms of trigonometric functions of the angle itself. The double angle theorem is the result of finding what happens when the sum identities of sine, cosine, and tangent are applied to find the expressions for $\sin (\theta + \theta)$, $\cos (\theta + \theta)$, and $\tan (\theta + \theta)$.
