So, we have this definite integral:

We find the indefinite integral as follows, by first finding the antiderivatives: After this, we take the derivative: And since we wanted the solution from the area of x = 0 to x = 1, we can ignore the second chunk, as it diverges and repeats infinitely. We only pay attention to the first two snippets, the 2x and the -x^3/3.Hope this helped!

TopNewestThe answer to the integral given was \(1+e^{-1}\) , can you help , it doesn't seems it matches with the series you gave, Btw., awesome approach!

Thank you! I'll have to look into it - my calc is a bit rusty :p @Sumukh Bansal and @Chung Kevin, Any help?
