Show that S sin(x) 1 + cos²(x) d.x NI: 2 Justify your answer fully. Let f(x) be continuous, and a be any constant. Explain carefully why [* ƒ(x) dx = ["* ƒ(a − x) dx. (c) [4 marks] Find π S™ x sin(x) 1+ cos²(x) dr. The results of parts (a) and (b) above can help. You may use without proof the identities sin ( + 0) = sin(0) and cos(π + 0) = = cos(0).
