Evaluate the integral. e36 sin 80 de Part 1 of 7 We will begin by letting u = sin 80 and dv = e36 de. 36 Then du = 8 cos ( 80) 8 cos (89) do and v = 3 3 Part 2 of 7 After integration by parts we have 36 sin (80) 36 sin 80 de = 1 sin(89) 8/3 8/3 3 cos 80 de 3 Part 3 of 7 We'll now apply the integration by parts procedure to the new integral 30 cos 80 de, letting U = cos 80 - and dV = e36 de. Then du = de and V =
