Homework Help: Partial derivative

  1. Aug 4, 2008 #1
    I have a question:
    Let w=2cot x +y^2.z^2
    x = uv
    y = sin(uv)
    z = e^v
    Find the partial derivative of w releative to x.

    Treat y^2.z^2 as a constant and derive with respect to x (the y^2.z^2 term will disappear). If you need any more help please post what you tried to do :).

    PS. Partial derivatives aren't really pre-calculus :P

    That's a pretty straight forward problem. You may be thinking it is harder than it is because, since u, v, and w are not present in the problem, the information you give: x=uv, y= sin(uv), z= ev is irrelvant. Please show us what you have done. In particular, what is the derivative of tan(x)?

    As focus said, this is not at all "precalculus". I am going to move this to the "calculus and beyond" homework area.
