(a) Find dy for each of the following. dx (i) y = In(sin- ((R+3)x2)) (ii) x' + 3cos(y]) =xy HIN (iii) y = (1+vx (Note: You are required to express the answer in terms of x ONLY) (b) Find the slope of the tangent to the graph of y = 2sin(xx - y) at the point (1, 0). (c) If f (x) = x +4x+3, find (f-' )'(-2)
