Scaling, stretching and shifting sinusoids
Read OriginalThis article provides a simple mathematical explanation of scaling, stretching, and shifting sinusoids. It covers how the parameters A (amplitude), w (frequency), and θ (phase shift) in the function s(x)=A·sin(w·x+θ) affect the waveform. The guide includes formulas for period calculation, examples of parameter changes, and a visual demo for experimentation. Aimed at a high-school math level, it demonstrates basic concepts of sinusoidal function transformation.
