Relative to the graph of y=3sinx what is the shift of the graph of y=3sin (x+pi/3)

The shifts of the sinus function can be described with the formula:

a sin (bx - c) + d, where

a is the amplitude

b is the period

c is the phase shift

d is the vertical shift

So, the graph y=3sinx is phase shifted. The phase shift can be calculated as c/b = pi/3/1=pi/3

So, the function is phase shifted for pi/3.
