Homework Help: Need help differentiating the following equation:

  1. May 19, 2012 #1
    1. I have this equation: y= 2.52e^-0.8472x which I need to differentiate.

    2. I am unsure whether to use the product or chain rule>

    3. I honestly don't know what to do...
    I was thinking 2.52e^u?

    Yes, let u=-0.8472x is how you could do it.

    Then, dy/dx = dy/du * du/dx
