How To Find Phase Shift Of Sine Graph. 👉 learn the basics to graphing sine and cosine functions. Find the phase shift for the function y = 3 cos (2x + 8).

A similar general form can be obtained for the other trigonometric functions. We reproduce the graph of 1.a below and note the following: 2.) determine the phase shift between the cosine function and the sine function.

### For Cosine It Is Zero, But For Your Graph It Is 3 Π / 2.

A similar general form can be obtained for the other trigonometric functions. Phase shift of sinusoidal functions. Now, the new part of graphing:

### 1 Small Division = Π / 8.

To find the phase shift from a graph, you need to: 👉 learn the basics to graphing sine and cosine functions. Determine the amplitude, period, & phase shift of a cosine function from its graph example 1:

### As You Can See, The Basic Shape Of The Sine Curve Is Still Recognizable — The Curves Are Just Shifted Up Or Down On The Coordinate Plane.

That is your phase shift (though you could also use − 3 π / 2 ). If the phase shift is zero, the curve starts at the origin, but it can move left or right depending on the phase shift.a negative phase shift indicates a movement to the right, and a positive phase shift indicates movement to the left.
