Amplitude (mathematics)

In mathematics, amplitude refers to the maximum extent or difference of a quantity's variation within a specific context. For example, in periodic functions like waves, amplitude measures how far the wave reaches from its resting position (the equilibrium point) to its highest or lowest point. It indicates the strength or intensity of the oscillation. Essentially, amplitude quantifies the "height" of a wave or the size of fluctuations in a set of data, helping describe the magnitude of variations in a clear, measurable way.
