Homework Help: Jacobian with two variables

  1. Apr 29, 2010 #1
    The variables u and w are related to x and y by the equations:

    u=(e^x)*cos(y) and w=(e^-x)sin(y)

    If I have the Jacobian for δ(u,w)/δ(x,y)

    How could I manipulate it to find (δx/δw)?

    With u held constant.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Try taking the inverse of the Jacobian.
