I have a function of the form
[tex]\int^{r}_{0} tf(t)dt[/tex]
I'm supposed to take the derivative with respect to r of this integral. By the fundamental theorem of calculus, is the derivative not
[tex]rf(r)[/tex]
The problem being I need, for the problem to work out correctly, to have a df/dr term. So, am I mistaken in my solution?
