Amplitude, Period, Phase Shift and Frequency . Some functions (like Sine and Cosine) repeat forever and are called Periodic Functions.. The Period goes from one peak to the next (or from any point to the next matching point):. The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.

The vertical shift comes from the value entirely outside of the trig function; namely, the outer 4 (also known as "D", from the formula). Because this 4 is subtracted from the tangent, the shift will be four units downward from the usual center line, the x -axis.

The phase shift formula for a trigonometric function, such as y = Asin(Bx - C) + D or y = Acos(Bx - C) + D, is represented as C / B. If C / B is positive, the curve moves right, and if it is negative, the curve moves left.

Since I have to graph "at least two periods" of this function, I'll need my x-axis to be at least four units wide. Now, the new part of graphing: the phase shift. Looking inside the argument, I see that there's something multiplied on the variable, and also that something is added onto it.

Phase Shift of Trigonometric Functions. The general form for the equation of the sine trigonometric function is y = A sin B(x + C) where A is the amplitude, the period is calculated by the constant B, and C is the phase shift. The graph y = sin x may be moved or shifted to the left or to the right.

Horizontal and Vertical Shifts Among the variations on the graphs of the trigonometric functions are shifts--both horizontal and vertical. Such shifts are easily accounted for in the formula of a given function. Take function f, where f (x) = sin(x). The graph of y = sin(x) is seen below.

In this section, we meet the following 2 graph types: y = a sin(bx + c). and. y = a cos(bx + c). Both b and c in these graphs affect the phase shift (or displacement), given by: `text(Phase shift)=(-c)/b` The phase shift is the amount that the curve is moved in a horizontal direction from its normal position. The displacement will be to the left if the phase shift is negative, and to the right ...

Phase shift is a small difference between two waves; in math and electronics, it is a delay between two waves that have the same period or frequency. Typically, phase shift is expressed in terms of angle, which can be measured in degrees or radians, and the angle can be positive or negative. For example, a +90 degree ...
