7 In this example, we will verify the identity 1+ tan? x = sec? r. (a) First, rewrite the left-hand side 1 + tan? x, in terms of sin x and cos r. (b) Next, add the two terms in the expression you got in part (a). (You need both terms to have a common denominator.) Cosco (c) Then, use the Pythagorean identity sin2 x + cos? x = 1 to simplify part (b). you got it in (d) Last, rewrite what you have in part (c) in terms of sec x. 2 CC Tatyana Khodorovskiy
