The range for cosine is , so the numerator . The entire fraction .
So, since . Can you get it from here?
I am suppose to use the comparison thereom to determine if the following integral is convergent or divergent
integral sign (S) a= e and b= infinity (2010 + cos 2011 x)/ 2009x dx
these numbers are huge and I don't know where to start - especially with a cos in the middle of it.
