The arc length of the curve is

which has a value of about 5.99086.
Let
. Split up the interval of integration into 10 subintervals,
[0, 1/2], [1/2, 1], [1, 3/2], ..., [9/2, 5]
The left and right endpoints are given respectively by the sequences,


with
.
These subintervals have midpoints given by

Over each subinterval, we approximate
with the quadratic polynomial

so that the integral we want to find can be estimated as

It turns out that

so that the arc length is approximately
