what if x appears inside the integral?
find f'(x) for f(x) = integral from a to b of g(x,t) dt
and then
use this result to evaluate I= integral from 0 to 1 of (t^2)*(e^(-t)) dt
and they give you a hint which makes no sense to me
Hint: Compute integral from 0 to 1 of e^(-st) dt
where s is a parameter
How is I related to this integral?
