Evaluate the integral. e38 sin(48) de Step 1 We will begin by letting u = sin(48) and dv = e39 de. Then du = sin 46 130 4 cos(40) de and v = 3 3 Step 2 After integration by parts we have e39 sin(48) de = sin(40)e3 4/3 'sin(40) 4/3 e39 cos(40) de- 3 Step 3 We'll now apply the integration by parts procedure to the new integral / e39 cos(48) de, letting U = cos(48) and dv = e39 de. Then du = de and V =
