Another improper integral solved using trapezoidal rule

In a previous post, I showed how Trapezoidal rule can be used to solve improper integrals.  The example used in the post was an improper integral with an infinite interval of integration.
In an example in this post, we use Trapezoidal rule to solve an improper integral where the integrand becomes infinite.  The integral is .  [...]

Can I use Trapezoidal rule to calculate an improper integral?

For example, is an improper integral which can be calculated exactly as .
Can we solve this integral by multiple segment Trapezoidal rule when we already know that the upper limit is infinity?
Yes, we can solve it in spite of the upper limit being infinity. We first need to make a change of variables such [...]
