Student solution. We begin by constructing a partition for the interval
into n equal segments. The width of each segment is
The partition points are as follows:
with the general term given by
Ik
From each segment [-1, T] with k = 1,2,...n in this partition, we choose r as the right-end point, namely
Then we have that
f(r) =|
We form the Riemann sum R, which is given by,
R, =
k1
Using the sum formulas according to the hint above, we simplify the Riemann sum to
R,
Next we have that
lim R,
This we obtain the integral equals
