I do not understand how to start this problem. I know I have to integrate from 0 to 1 and that n=3 but thats all. Hints/clues appreciated!

Hint - Check the different sums given in (a)-(e), and take into account that:
== The function must be evaluated in points of the given subintervals $\,[x_i,x_{i+1}]\subset [0,1]\,$ , and way more important:
== Every value of the function must be multiplied by the correspoding subinterval's length!

0Yes, indeed (b). Can you explain why the $\,2\,$ before the first summand, though? Also observe that (c) *almost* makes it...what's the problem with it, though? – 2012-11-24
