Trig Functions | Overview, Chart & Graphs

Triangular functions are periodic mathematical functions that model repeating linear patterns found in nature and engineering. Unlike smooth trigonometric functions such as sine and cosine, triangular functions consist of straight-line segments that rise and fall linearly, forming a triangular or sawtooth-like wave. Mathematically, they can be defined using piecewise linear equations or expressed as Fourier series of sine terms. Their simplicity and harmonic richness make them useful in signal p
