sinusoideális
Sinusoideális refers to a mathematical concept closely related to the sine function and its properties. It describes a waveform that can be represented by the sine function or a cosine function. These waveforms are characterized by their smooth, continuous, and repetitive nature. They oscillate between a maximum and minimum value with a specific frequency and amplitude. The term is often used in physics and engineering to describe phenomena such as alternating current (AC) electricity, sound waves, and light waves. A pure sinusoidal signal is considered the simplest form of periodic oscillation. Mathematically, a sinusoidal function can be expressed in the general form A sin(ωt + φ) or A cos(ωt + φ), where A represents the amplitude, ω is the angular frequency, t is time, and φ is the phase shift. The shape of a sinusoideális curve is a smooth, repeating wave.
