Default Calculus help needed

My mind went blank and I can't do the following:

Maximize R(t) = 50t / (t^2 + 36)
t >= 0

Somehow I forgot how to find the derivative!

Oh also I need to find the marginal revenue function of the following:
R(x) = 1000xe^(-x/50)

d/dt = -50*(t^2-36)/(t^2+36)^2
This is a limit as t approaches infinity, and is always larger than 0, correct?

I don't know about marginal revenue functions. Is that Net Present Value?
