The addition formulae and trigonometric identities are used to simplify or evaluate trigonometric expressions. Trigonometric equations are solved using a double angle formulae and the wave function.

For high-output precision, the lookup table size is often too large for practical use. This brief investigates the so-called $ (M,p,k)$ scheme that reduces the range of an input argument to a very ...

In this section you will: * Find exact values of the trigonometric functions secant, cosecant, tangent, and cotangent of π 3 , π 4 , and π 6 . Use reference angles to evaluate the trigonometric ...
