Differentiate xe^x csc x?

  1. Feb 24, 2009 #1
    I dont really know how to even start this problem because I dont think the product rule would work here since there are three variables, right?

    Here is my attempt at it:

    xe^x csc x

    xe^x csc x + xe^x (-csc x cot x)

    xe^x (csc x - csc x cot x)

    Used the product rule and thats what I came up with, can anyone give me a hint at what the first step is at least?

    You can easily extend the product rule to three terms. (fgh)'=f'gh+fg'h+fgh'.

    thanks, that makes a lot more sense :)
