Another Integration by Parts problem I keep getting almost right!
My work is attached.
The final answer in my text book is the same that Wolfram Alpha provides:
integral (arctan(4x - Wolfram|Alpha))
but Wolfram Alpha does not show the work for this integThe final answer in my text book is the same that Wolfram Alpha provides:ral; it says "$Aborted" whenever I ask it to show the steps.
My work is different according to this in Wolfram Alpha: is 1/8 * ln(1 + 16x^2) = 2ln(x^2 +1) ?
If they are equal, it returns true, otherwise it shows the usual data. And, it does not return true, so they are not equal.
Any help would be very much appreciated!
