It is not useful for certain unreduced trigonometric functions because it simply rearranges the trigonometric operators, but it can be used to evaluate the limit of many expressions in which a function is divided by, multiplied by, or taken to the power of another function.
It is used to prove that the Laplace transform of a square wave has poles at all values where the denominator of the transform equation equals zero. It can be proved by performing a Taylor expansion on an eligible equation and using the extended mean value theorem.

Used to solve improper integrals, for ten points, name this rule for finding limits of functions when the component functions themselves approach zero or infinity.
