WebThe Trigonometric Functions Let us return to the diagram of the right-angled triangle. There are a number of relations between the sides a, b, and c and the angle φ.These are called the Trigonometric Functions.. There are three main Trigonometric Functions. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle … See more By examining the unit circle, one can establish the following properties of the trigonometric functions.
