Homework Help: Problem solving a separable differential equation for u

  1. Sep 17, 2013 #1
    1. The problem statement, all variables and given/known data
    Solve the separable differential equation for u


    Use the following initial condition: u(0)=13

    3. The attempt at a solution

    Honestly I didn't get very far on this one. I took the natural log of both sides,

    ln du/dt = 5u+2t

    And now I am stuck. Should I divide both sides first by our e^(5u+2t) instead of taking the ln?

    Hint: Use the laws of exponents to split e5u + 2t.
