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.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
