What is a phase of a wave and a phase difference?
— If you make an arbitrary choice and say your wave "starts" when it's height is 0, then if you start a second wave a short time later it will be out of phase with the first wave. If you start the second wave at a later time that is an exact multiple of the time the first wave takes to repeat, the second wave will be in phase.

What is a Sinusoidal Wave Signal – Definition and Importance
— A sinusoidal wave signal is a type of periodic signal that oscillates (moves up and down), periodically. The geometrical waveform of a sinusoidal signal forms an S-shape wave in one complete cycle. A sinusoidal can be a sine functioned signal or cosine functioned signal. Thus, a sinusoidal signal can be defined as,

9.2: Sinusoidal Waveforms
Further, if a sine wave is shifted by +90 degrees (i.e., leading and to the left), it may also be referred to as a cosine wave. Thus (sin (2 pi ft + 90^{circ}) = cos (2 pi ft)). Finally, if a sine wave is shifted by −90 degrees (i.e., lagging and to the right), it may be referred to as a negative or inverted cosine wave.

Sinusoidal Wave Displacement Function
$begingroup$ I am aware of the identity, but sin(x) and cos(x) on their own, are not equal. Therefore, sin(kx - wt) is not equal to cos(kx - wt).So when I'm given a question say: Write down the displacement function of a sinusoidal wave with A = 2.0, k = 4.0 and w = 1.5, would I write it as y(x,t) = 2.0cos(4x - 1.5t) or y(x,t) = 2.0sin(4x - 1.5t)?Forget about trig …

With sinusoidal functions, frequency is the number of cycles that occur in (2 pi). A shorter period means more cycles can fit in (2 pi) and thus a higher frequency. Period and frequency are ...
Sinusoidal Wave
A sine wave or sinusoidal wave is the most natural representation of how many things in nature change state. A sine wave shows how the amplitude of a variable changes with time. The variable could be audible sound for example. A single pure note is a sine wave, although it would sound a very plain and flat note indeed with none of the harmonics we …
