calc 1.3_Limits Involving Trigonometry

Limits involving trig functions. Students should already be familiar with the Squeeze Theorem (a.k.a. Sandwich Theorem) and how it led to evaluation of the limit of sin(x)/x as x approaches 0.
ERROR: At 10:54 I write on the screen that the limit =1 (which is correct), but then I say that as the x value approaches 0 the y value also approaches 0 (oops, that's wrong, meant to say 1).
