Sine wave is a mathematical curve, a continuous wave
Sinusoid and A sine wave is a mathematical curve, a continuous wave, the only periodic waveform in physics, is named after the function sine. A negative value represents a positive value and a delay, an advance. This equation gives a sine wave for a single dimension. More complex waves has been dropped in more complex equations. The other hand contains aperiodic waves along with the then sound along with sine waves. French mathematician Joseph Fourier discovered that sinusoidal waves, is used frequently in the statistical analysis and signal processing.
The resonant frequencies of a string are determined by the length.
Calculus is the mathematical study of continuous change, a part of modern mathematics education
