Geometric Construction for the Limit as x approaches 0 of sin(x)/x

This applet shows that the area of the small triangle is smaller than the area of the sector, which in turn is smaller than the area of the big triangle. This inequality of areas allows one to compute the limit as x approaches 0 of the function sin(x)/x using the Squeeze Theorem.
