Unified Calculus II : Homework Set 1 1. Let f(x) = 2x3 + 5, find f-1(y). 2. Let f(x) = $12. is f one to one? If so find f-1(y). 3. Find (a) arcsin(-?), (b) arccos (sin()), (c) cos (arcsin(-?)) 4. Find f'(x) where f(x) is given as follows, (a) f(x) = arcsin(2x2 + 1), (b) f (x) = arctan(V1 + 22), (c) f(x) = cos(arctan(x)). 5. Find the following integrals ( a) S dx T 2 - 41+5' (b) J V 12-12 + 4x dx
