I have been able to process this question a little bit, but got a bit stuck when i got to a certain point..
Express the integral as a limit of sums;
So by setting and
But form here I dont know if i have done something incorrectly, or how to keep reducing it to get rid of n..
Ah yes, that makes sense. Thanks allot for that.
I actually just re-read the question, and it says to use a computer to calculate the sum and the limit... Is there away to analyse trigonometric functions using riemann sums without a computer for exam preperation(ie. can this question be taken any further)?
