1. The problem statement, all variables and given/known data Derive cube root formula using Newton-Rhapson's method. x - y^3 = 0. 2. Relevant equations xn + 1 = xn - f(xn)/f'(xn) 3. The attempt at a solution I know that the solution is (2y + (x/y^2))/3 I tried using implicit differentiation and stuff but I can't get this out. Any tips?
