so basically u need to take the integral of first one right
if so use u subsitution
integrate by parts i can do the integrate by parts but i do not know what to do after that e^x(1-2x)^n - ∫-2ne^x(1-2x)^n-1 dx now what?
thank you so much now one question why do you label that In-1?
because it's In where you sub n with n-1
thank you very much perfect! So just to be clear if i am subbing in limits i sub them in the left and the right side of my In?
