TRIGONOMETRIC IDENTITIES EXPLAINED

Trigonometric identities are fundamental equations involving trigonometric functions that hold true for all values of the involved variables (typically angles) where both sides of the equation are defined. These identities are used extensively in geometry, calculus, physics, engineering, and many areas of mathematics.

1. Basic Trigonometric Functions

Sine (sin), Cosine (cos), and Tangent (tan) are the primary trigonometric functions.

Other functions include Cosecant (csc), Secant (sec), and Cotangent (cot), which are reciprocals of sine, cosine, and tangent respectively.
