Below

Explanation:

y=sin(x-pi/3)y=sin(xπ3) is your y=sinxy=sinx graph but shifted to the right by pi/3π3 units

y=asin(nx+b)y=asin(nx+b) is the general form
aa is the amplitude
nn is used to find the period of the function
bb is the shift to left or right

Therefore, wtih reference to the general form, y=sin(x-pi/3y=sin(xπ3 has an amplitude of 1, a shift to the right by pi/3π3 units.

The period is found using this equation
T=(2pi)/nT=2πn
T=(2pi)/1T=2π1
T=2piT=2π
That means the graph finishes one cycle in 2pi2π

Below is y=sinxy=sinx

graph{sinx [-10, 10, -5, 5]}

Below is y=sin(x-pi/3)y=sin(xπ3). Notice that it is exactly the graph y=sinxy=sinx but moved to the right by pi/3π3 units

graph{sin(x-pi/3) [-10, 10, -5, 5]}
