### Limit of a function: Pinching theorem with streamlined method of solution

Free ebook http://tinyurl.com/EngMathYTI discuss and solve an example involving the limit of a function and an application of the pinching theorem. Such a theorem involves inequalities and is seen in 1st year university mathematics. Note that I present a streamlined method of solution. As a result there is no need to split the method of solution into the cases: $x$ is positive; and $x$ is negative.
