Sine and Cosine Waveforms Visualization - Phase Shifts & Harmonics #1775257 (License: Personal Use)

This graph displays eight periodic waveforms-combinations of sine and cosine functions-each shifted in phase and color-coded for clarity. The x-axis spans from 0 to 1 (normalized period), while the y-axis ranges from -1 to 1, representing amplitude. The overlapping curves demonstrate how phase differences create interference patterns essential in Fourier analysis and AC circuit theory.

Used in educational content on trigonometry, signal processing, or physics to illustrate wave behavior, superposition, and harmonic decomposition; targets students, engineers, and educators seeking visual intuition.
