Product rule

  1. Mar 16, 2014 #1
    y=3x2Inx

    u=3x2
    v=Inx
    du/dx=6x
    dv/dx=I/x

    y=u*v

    dy/dx=(u)(dv/dx)+(v)(du/dx)

    dy/dx=(3x2)(I/x)+(Inx)(6x)

    Can I simplify this further

    What is Inx? If you are going by what is on a button on a calculator, that is ln x (LN), for natural logarithm.
    If v = ln(x), then dv/dx = 1/x, not I/x.
    Please post homework-type problems in the Homework & Coursework section, not in the technical math sections. I am moving this thread.

    It's not homework!

    But it's a homework-type problem, so this is where it goes.
