Introduction to Trigonometry

The video is a brief introduction to or review of trigonometry. The teacher uses a spray bottle to show the difference between opposite, adjacent, and hypotenuse according to the angle in which the bottle is located. Then she touches upon sine, cosine, and tangent. She uses theatrics to introduce the saying "soh-cah-toa" as an acronym for each of the sine, cosine, and tangent.
