The following is similar to the proof given in the pdf above but was nice enough and easy enough (I hope) that I wanted to include it here.

And $\frac{1}{x^2}$ certainly approaches zero. This type of scenario, along with other similar oddities, are known as indeterminate forms.

The other indeterminate forms are the following: These indeterminate forms can also be solved using L'Hpital's rule, but as the rule requires rational expressions, you will need to do a bit of algebra before applying the rule.

unimaginable amount.

After subtracting (or, in some scenarios, adding) the fractions, you will be left with a rational expression, so you can use L'Hpital's rule if the limit does not evaluate directly.

Depending on the relative size of the two integers it might take a very, very long time to list all the integers between them and there isnt really a purpose to doing it.

In a mathematical expression, indeterminate form symbolises that we cannot find the original value of the given decimal fractions, even after the substitution of the limits.

In particular, infinity is the same thing as "1 over 0", so "zero times infinity" is the same thing as "zero over zero", which is an indeterminate form.
