Be able to use radians to graph sinusoid equations and predict the outcomes based on the concepts in the reading. We'll listen to various sinusoids in VAB, see how sine is generated, and discuss the sinusoid basic formula for periodic waveforms. If you're in Calculus this won't be a stretch :-)

You'll need to memorize the basic form of a periodic audio signal = signal over time (t) =

s(t) = Amplitude* cos ((2pi*frequency)t) + phi;

where phi is the phase shift or delay/gain in the timing of the sinusoid (where it crosses the y-axis).
