I have an equation like this:
$te^{t} = \int\nolimits_0^t e^\tau u(\tau)d\tau$
I don't really know how to solve it.. Would it be possible to differentiate both sides of the equation? If so, how can I do it - is it like differentiate one side and then the other or is it more complex? And if it is possible what conditions need to be satisfied in order to do it?
