Trigonometric Identities
Trigonometric Identities refer to mathematical equations that involve trigonometric functions such as sine, cosine, and tangent. These identities are used to simplify trigonometric expressions and equations by establishing relationships between different trigonometric functions. Common identities include the Pythagorean identities, sum and difference identities, double angle identities, and half angle identities. These identities are fundamental in trigonometry and are essential for solving various mathematical problems involving angles and triangles.
