Hard Implicit D. question

  1. Oct 11, 2005 #1
    How do I correctly differentiate this using implicit differentiation:

    xy^1/2 = 1 + x^2y

    I got to here before I started wondering how I would properly isolate y':

    ((1/2xy)^-1/2)y + y'x = 2xy + x^2y'

    How far off the beaten path am I on this? :grumpy:

    The right hand side of your equation looks OK. Redo the left side.
