CLEP Precalculus covers essential mathematical concepts and skills necessary for success in calculus and higher-level mathematics.
Trigonometric functions are at the heart of sound waves. Sine and cosine functions can describe the pitch, volume, and timbre of every note you hear.
A sound wave can be modeled as \( y = A\sin(Bt + C) \), where \( A \) is amplitude, \( B \) relates to frequency, and \( C \) is phase.
Audio engineers use these equations to mix music, reduce noise, and even create digital instruments.
Modeling a musical note as \( y = 2\sin(440\pi t) \).
Using trigonometric graphs to design headphones that reduce unwanted sounds.
