In mathematics, trigonometric identities are equalities Pythagorean identity. The basic relationship between the sine and the cosine is the Pythagorean trigonometric identity: where cos2 ? means (cos(?))2 and sin2 ? means (sin(?))2. This can ..

Very often it is necessary to rewrite expressions involving sines, cosines and tangents in alter- native forms. To do this we use formulas known as trigonometric identities. A number of commonly used identities are listed here: 1. The identities. tanA = sin A. cosA sec A = 1. cosA cosec A = 1 sin A cot A = cosA sin A. = 1. tanA.

In this section, we will turn our attention to identities. In algebra, statements such as 2x x x, x3. x x x, and x/(4x). 1/4 are called identities. They are iden- tities because they are true for all replacements of the variable for which they are defined. The eight basic trigonometric identities are listed in Table 1. As we will see, they are

The Elementary Identities. Let (x, y) be the point on the unit circle centered at (0,0) that determines the angle trad. Recall that the definitions of the trigonometric functions for this angle are sint = y tant = y x sec t = 1 y cost = x cott = x y csc t = 1 x . These definitions readily establish the first of the elementary or fundamental.
