Answer:
Step-by-step explanation:
Answer:Commutative Property
Step-by-step explanation:
For the first question, the region is a bit ambiguous.
and
intersect three times, and there are two regions between them. So either you're approximating
or
I'll assume the second case. Split the interval into 4 smaller ones, taking
with respective midpoints of
. The length of each interval is
. Note that I'm also assuming you are supposed to use equally spaced intervals.
Skipping the second one since I already answered it.
For the third, split up the region of integration at some arbitrary constant
between
and
, then differentiate and apply the fundamental theorem of calculus.
Since
, it follows that
is constant.
