I tried typing this into the wolfram alpha app " ??xcosy dydx , y from 0 to x^2 , x from 0 to 1 " I got an answer of " sin^2(1/2)= 0.2298.. " But the answer (as far as I can tell) should be 0.5 What's happening here?
Guys , thank you. It's my bad , I just made a miscalculation that's all , I will be more careful before posting next time.
I caluculated "by hand" and get 0.229849 too.
Did you integrate by parts?
Thanks for your reply Baldwin , it was just a miscalculation. I'm sorry
