To determine

**To show:**The function

Expert Solution

**Given information:**The function is

**Proof:**

It is known that a function

Consider that the number of rectanglesof subintervals for

If left endpoints is used then the height of the first rectangle be 0 because

The area of the first rectangle is as follows:

The function

Now, increase the value of

The first term and the entire sum tendtowards infinity. A function is not integrable on a certain interval if the sum tend towards

Hence, it is proved that the function is not integrableon
