The shifts of the sinus function can be described with the formula: <span>a<span>sin<span>(<span><span>bx</span><span>−c</span></span>)</span></span></span>+<span>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.</span>
