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.
know the identities associated with sin2 ? + cos2 ? = 1,. • know the expressions for sin, cos, tan of sums and differences of angles,. • be able to simplify expressions and verify identities involving the trigonometric functions,. • know how to differentiate all the trigonometric functions,. • know expressions for sin2?, cos2?, tan2?
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

In the last two chapters we have used basic definitions and relationships to simplify trigonometric expressions and equations. In this chapter we will look at more complex relationships that allow us to consider combining and composing equations. By conducting a deeper study of the trigonometric identities we can learn to
