RECALL:
The graph of $y=\cos{(x-d)}$ involves a horizontal shift of the parent function $y=\cos{x}$. The shift is $d$ units to the right when $d \gt 0$ and $|d|$ units to the left when $d\lt0$.
The given function has $d=\frac{\pi}{2}$, which is positive.
Thus, the given function involves a $\frac{\pi}{2}$-unit shift to the right of the parent function $y=\cos{x}$.
To graph the given function, perform the following steps:
(1) Graph the parent function $y=\cos{x}$ over a two-period interval, which is $[0, 4\pi]$.
(Refer to the red graph in the answer part above.)
(2) Shift the graph of the parent function $\frac{\pi}{2}$ units to the right.
(Refer to the blue graph in the answer part above.)
