Need a little help on the homework in the calculus book...

I need to use an example to prove that Lim [F(x)+G(x)] as X approaches A may exist, even if neither Lim F(x) as X approaches A nor Lim G(x) as X approaches A exist.

I know this has something to do with the "Pinch" Theorem, but I really don't know where to go with this.

Thanks!
