The area of a triangle in terms of its semi-perimeter and side lengths can be written as. Opposite sin hypotenuse q hypotenuse csc opposite q adjacent cos hypotenuse q hypotenuse sec adjacent q opposite tan adjacent q adjacent cot opposite q Unit circle definition For this definition q is any angle. Trigonometric Identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined.

The upcoming discussion covers the fundamental trigonometric identities and their proofs. Each of the six trig functions is equal to its co-function evaluated at the complementary angle. Theres not much to these.

For right trianglesThere are loads of trigonometric identities but the following are the ones youre most likely to see and use. These can be trivially. These identities are true for all values of the variables.
