Homework Help: Integrating a power of e

  1. Nov 14, 2009 #1
    1. The problem statement, all variables and given/known data

    Needing to integrate 3ye^3z dz

    2. Relevant equations

    3. The attempt at a solution
    I believe you use u substitution and u=3z du=3dz
    Then you get yze^3z. Is this correct?

    If you differentiate yze3z with respect to z do you get what you started with? I don't think so, but can you fix it?

    >>Then you get yze^3z. Is this correct?
    No completely, you have an extra factor of z

    I believe differentiating ye^3z with respect to z will give 3ye^3z. Therefore, integrating 3ye^3z dz will be ye^3z. Correct?
