(a) For the function f(x) =x^2/x^3+1
, find the slope of the tangent line at x = - 1. Hence,
write down the equations of the tangent line and the normal line. / (3+2+2)
(b) Using the first principle of differentiation, find the left hand and the right hand
derivatives of f at x = 0: f(x) ={2x+1 if x<0
