**calculus**

is it because every interval of one the integrals approach 1?
*February 24, 2010*

But how did you arrive at "as N gets big this looks like e^x(-NcosNx)/N^2?????
*February 19, 2010*

**Calculus**

Now how would you describe the graph of this function when say N=5, N=10, and N=100? And what does it mean does the graph confirm the limiting behavior of the integral's value?
