Its an old IIT-JEE question [Paper 1,JEE 2008,Q.20] Consider the function defined implicitly by y^3 - 3y + x =0 on various intervals. If x belongs to (-2,2)the equation implicitly defines a unique real valued differentiable function y=g(x) satisfying g(0)=0 then (I'm writing in words because i can't get the symbols) Integral(-1 to +1) g'(x) = [g'(x) is derivative of g(x)] answer given is 2g(1). How to get it?
