The more theoretical details, it smells like some flavor of the Fundamental Theorem of Calculus or Leibniz's Rule but I'm lost:

Differentiate with respect to t:

d/dt [

**t**+ Integral(

**m(t-x) dx**, 0, t) ]

It's supposed to evaluate to 1 + m(t). I see where the 1 comes from but I don't know anything about m(t) though so there has to be a general principle...

Thanks
