Hello. Is there anybody could help me to integrate this with Wolframalpha.com . From a) I need Step By Steep to get b). Thanks
I don't have Pro for students in Wolfram|Alpha.
If Pro doesn't work for you use for example: www.symbolab.com:
See: Free alternative to step-by-step-solution feature of Wolfram|Alpha Pro?
1 hour and more than 150 views and there is not anybody here that can respond why Wolframalpha Can't solve that simples integrals?
Maybe WolframAlpha and Mathematica are not too much powerful as we think.
THank you! it should be solved with a change of variable with tan but I dont find one that works
