Hi. I need help with a Maths number.
∫ f(x) dx = (b^2) (e^b) - e
where the upper limit of the integral is b and the lower limit is 1. Also, b > 0
Find an expression for f(x) for all x>0.
I know I have to differentiate the b(sqaure) * e(to the power of b) - e, but I don't really know how to do it since there are no x in the expression. I know I should be using the limits of the integrals as well but I don't know how :/
Help! Thanks x
