how can i integrate,
Sir plse ans this ques.
Is the integral?
I don't think that integral has a closed form solution, but you can get one in the form of a Taylor series.
zetafunc is right. Probably no closed form answer. Have you copied the question right?
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
