Write the expression as either the sine, cosine, or tangent of a single angle. sin(pi/2)cos(pi/7)+cos(pi/2)sin(pi/ 7)

.

Step-by-step explanation:

We have been given a trigonometric expression . We are asked to write our given expression as either the sine, cosine, or tangent of a single angle.

Using identity , we can rewrite our given expression.

Let and .

Upon substituting these values in above identity, we will get:

Upon simplifying right side of our equation, we will get:

Therefore, our required expression would be .

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
