/ 1. Given x2y+ey + ycosx = 0. Carry out implicit differentiation to obtain %in terms of x and y. Then nd the gradient of the tangent to the curve at2 y + e\" + y cos x = 0 at the point (0,1). 2. Given f (x) = 2x3 3x2 12x , nd the absolute minimum and absolute maximum value of f over the interval [0,3] and state where the absolute value occurs
