Introduces the topic of trigonometry. The sine and cosine are first derived from the unit circle, and then their basic properties and identities are explored. The use of sine and cosine in the use of harmonic motion is illustrated visually and audibly with an electronic synthesizer and with musical instruments. The periodic nature of the sine wave is discussed, and the traditional triangular derivation of the sine and cosine is presented.
