(N/A) The graph of displacement $x$ versus time $t$ represents the displacement as a continuous function of time. This is given by the equation $x(t) = A \cos(\omega t + \phi)$.
Here,$A$,$\omega$,and $\phi$ are constants that determine the characteristics of $SHM$.
The graph of displacement as a continuous function of time for simple harmonic motion is shown below:
[Graph showing a cosine wave starting at $x = A$ at $t = 0$,oscillating between $A$ and $-A$]
The standard symbols in the equation $x(t) = A \cos(\omega t + \phi)$ are defined as follows:
$x(t)$: Displacement $x$ as a function of time $t$
$A$: Amplitude
$\omega$: Angular frequency
$\omega t + \phi$: Phase (Time-Dependent)
$\phi$: Phase constant
