Differentiation, I'm I doing it right?

    1. The problem statement, all variables and given/known data
    Uploaded on the bottom
    2. Relevant equations
    3. The attempt at a solution
    I took dt of both sides. The part that confuses me is when you take the derivative of 1 over t . The one becomes a 0 and the t becomes a dt. Just want to make sure I did that right.

    If you are taking the derivative of 1/t think of it as ##t^{-1}## and apply the rule for powers.

    So it would be , -t^-2?

    Edit: crossposted. You are on the right track now.

    You should not end up with ## dt ## on its own. Go back to your notes and look at how to differentiate two terms added together, and how to differentiate ## x^n ## (bearing in mind that ## x = x^1 ## and ## \frac 1x = x^{-1} ##).
