Differentiation - cant remember

  1. Jul 14, 2010 #1
    1. The problem statement, all variables and given/known data

    for the question and attempt see the attachment. ive nearly done this but from my ti-89 I know that i am missing a 2x from the top line and i cant find where its gone. been a while since ive done this and i think that its just a simple mistake... ps it does want the double differential but once i get the first diff right i should be able to finish it off...... thanks for any help.

    2. Relevant equations



    3. The attempt at a solution

    The 2x is missing because you forgot that you need to use the chain rule.
