Squeeze Theorem

After answering questions from last night's homework for about half the period, we started looking at a new algebraic technique to possibly evaluate limits of indeterminant form -- the Squeeze Theorem, or sometimes called the Sandwich Theorem.  Basically, we are looking at evaluating a limit for a function that we cannot seem to do.  Instead, we'll find a "back door" way to find its value, by coming up with two boundary functions (one larger than f(x), one smaller), whose limits do exist as x approaches a and are the same value, and we'll force the function in question betweenL and L.  We then used this squeeze theorem technique to look at the lim (sin x)/x as x approaches 0, but ran out of time about halfway through.  We'll pick up class tomorrow at this point.
