I was having trouble starting up this question.
Let
 2, if x<6
f(x) ={ 7, if x=6
3, if x>6.
Compute (the integral from 3 to 11) f and prove that your right.
The problem i was having was choosing a partition for this integral.
For example, [3,x,y,11], what type of values could i use that are close enough to 6. Is 5 and 7 close enough? or something like +/ epsilon/2(this part is what confuses me, the epsilon)?
