Best ResponseYou've already chosen the best response.1I got \[\frac{1}{2\sqrt2}*\ln\csc(2x+\pi/4)\cot(2x+\pi/4)\] can anyone check if it's the right answer?

Best ResponseYou've already chosen the best response.1i tried to integrate on wolfram alpha, it gives me something else. To check if they are equal, I plugged a number for x in both equations, but got different answer.. :O is that normal?

Best ResponseYou've already chosen the best response.3i think they will be equivalent, with just different form, which value you tried ?

Best ResponseYou've already chosen the best response.3i checked, it comes out to be different. also i missed earlier that integral of cosec x is ln cosec x + cot x+c and you've typed  *minus*

Best ResponseYou've already chosen the best response.3but our method is correct, maybe it comes different because of the constant '+c' which might be different for both forms....

Best ResponseYou've already chosen the best response.1hey!!! i got it, if i calculate the \[\int\limits_{a}^{b}f(x)\] of both equations, it gives the same value if a and b are the same, so it's correct! Also thanks a lot for spending so much time on this, I really appreciate it!
