I am also stumped on another question which is probably easy for one of you the question is
Evaluate
the integral from 1 to 1 (sinx)/(1+x^2)dx <x in the denominator is being raised to the second power not everything sorry i do not know a better way of inputting this.
I was wondering if someone may be able to solve this rather quickly, i have NO Clue what so ever to even begin doing this, this was an extra assignment that was given to us today and due tomorrow 72809. Please answer asap, thank you very much for your help on the last problem and thank you in advance.
P.S. i am sorry for posting in the wrong section, these questions come from my calc class.
