Homework Help: Differentiation of log function

  1. Jul 20, 2010 #1
    1. The problem statement, all variables and given/known data

    Find an equation of the tangent line to the curve at the
    given point.

    y = ln(xe^(x²)) P=(1, 1)

    3. The attempt at a solution

    I know how to plug in the numbers into the Point-Slope formula once I find the derivative of the function, or slope, I'm just not sure how to derive this function.

    First, use the properties of logarithms; namely ln(a*b) = ln a + ln b. Then, take the derivative. Presumably you know how to differentiate y = ln u, where u is a function of x.

    Yes, thank you!
