Implicit Differentiation Question - Stuck

  1. Apr 24, 2013 #1
    Hi, I'm doing an online course for Calculus 12 and I have been struggling with Implicit Differentiation, hoping someone could maybe help me. Thanks.

    I'm not positive I'm doing this right but maybe someone can point me in the right direction, this is what I have so far

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

    y=(x^2+1)(x-y)

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

    y' = 2x^2-2xy+x^2-x^2y'+1-y'

    This is where I get stuck and am not sure if I'm making a mistake or know what to do next. Any help would be appreciated, thank you.

    Hey playdohh.

    What you've done is right. Just collect the y' terms on one side and you're done.
