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?
In mathematics, you don't understand things. You just get used to them.
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.
