Sometimes, none of the previous strategies are particularly helpful when trying to resolve the indeterminate form of 0/0.  Here we present our final strategy, The Squeeze Theorem.  Surely, Lord Voldemort would approve.  Duration: 14:15 

More or less, the entire reason we learn about The Squeeze Theorem is to show that lim(x→0)sin(⁡x)/x=1.  Why couldn't we just look at a graph?  Duration: 4:14 

So it turns out that we did look at a graph, which isn't particularly rigorous.  On Example 16b, we attempt to reassert some of that rigor.  This one sort of ends on a cliffhanger.  Duration: 9:51 

What do you think?  Where you able to successfully wave a trigonometric wand over your inequality to magically transform it into something more applicable to the problem at hand?  Regardless of your success, this video will be that much-needed incantation.  Duration: 13:35

Using Two Special Trig Limits, we are able to use clever substitution to evaluate a couple of limits.  Commit those special limits to memory.  Duration: 8:55
