How To Find Phase Shift From Equation. To graph a sine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/. An easy way to find the phase shift for a cosine curve is to look at the \$x\$ value of the maximum point.

Remember that the phase shift, from your function in standard form is c / b. In the case of above, the period of the function is π. In our case, the phase shift formula gives:

### The Period Is 2 /B, And In This Case B=6.

Vertical shift = 3 positive value indicates the centre line is y = +3. If c / b is positive, the curve moves right, and if it is negative, the curve moves left. In the graph of 2.a the phase shift is equal 3 small divisions to the right.

### Phase Shift Is C (Positive Is To The Left) Vertical Shift Is D;

Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation. , where we're assuming an equilibrium shift of 0. We use the general form:

### Period = 2Π/B Here B Value Is 100.

Calculation between phase angle φ° in degrees (deg), the time delay δ t and the frequency f is: And here is how it looks on a graph: Phase shift is measured as the angle (in degrees or radians) between two points on a circle at the same time, demonstrating the progress of each wave through its cycle.
