(if the quantity diverges, enter diverges.)

The improper integral converges and .

Step-by-step explanation:

First, I assume that the integral in question is

.

Now, the integral is improper because, at least, one of the limits is . We need to recall that an improper integral

converges, by definition, if the following limit exist:

.

In this particular case we need to study the limit

.

In order to complete this task we calculate the integral . Then,

.

Substituting the above expression into the limit we have

because

.
