WebOne period of cos(x) is 2π, but one period of cos(2x) is π. In other words, "period" is descriptive of a specific function, not of whatever function you perceive to be the "underlying function". ... Well, if you think about just a traditional cosine function, a traditional cosine function or a traditional sine function, it has a period of 2 ... WebJan 9, 2024 · For example, a sine function is a continuous signal, as is an exponential function or a constant function. A portion of a sine signal over a range of time 0 to 6 seconds is also continuous. Examples of functions that are not continuous would be any discrete signal, where the value of the signal is only defined at certain intervals.
Weball periodic functions are not sinusoidal functions. sinusoidal function or sinusoidal wave is a curve that describes a smooth repetitive oscillation. But a rectangular, triangular, square waves, trapezoid waves and saw tooth waves are also exhibits a repeating pattern just like a sinusoidal wave. ... WebDec 30, 2024 · Combining the dependencies on space and time in a single expression, we can write for the sinusoidal wave: (9.1.1) u ( x, t) = A cos ( k x − ω t) Figure 9.1. 1: Two basic types of waves. (a) Longitudinal wave, where the oscillatory motion of the particles is in the same direction as that of the wave. (b) Transverse wave, where the ...
