Determine the amplitude, period, and phase shift of `y=(1)/(2)cos((1)/(2)x-(pi)/(3))` and sketch at leasst one period of the graph.

Explanation

To determine the amplitude, period, and phase shift of the function \( y = \frac{1}{2} \cos\left(\frac{1}{2}x - \frac{\pi}{3}\right) \), we will compare it with the standard form of a cosine function, which is given by:

\[ y = a \cos(bx - c) + d \]

### Step 1: Identify the parameters \( a \), \( b \), and \( c \)
