Homework Help: Implicit Differentiation?

  1. May 8, 2014 #1
    1. The problem statement, all variables and given/known data

    Differentiate using implicit differentiation y^2sin(x)

    2. Relevant equations

    I know you need the chain rule and the product rule to solve this

    3. The attempt at a solution

    So, it would be:

    2yy' + y^2cos(x)

    Is that correct?

    No. Your expression is a product, so you need to use the product rule first.

    d/dx(y2sin(x)) = ?

    Oops! It should have been 2yy'sin(x)+y^2cosx

    That is correct.
