# What is a phase shift of pi?

## What is a phase shift of pi?

Phase shift is the horizontal shift left or right for periodic functions. If c=π2 then the sine wave is shifted left by π2. If c=−3 then the sine wave is shifted right by 3.

## What is phase shift of a function?

Phase Shift is a shift when the graph of the sine function and cosine function is shifted left or right from their usual position or we can say that in phase shift the function is shifted horizontally how far from the usual position.

**What is the formula of shift?**

Using Phase Shift Formula, F(x) = Asin(Bx−C) + D. Answer: The phase shift of the given sine function is -3/4.

**How do you find the phase?**

Dividing the frequency into 1 gives the period, or duration of each cycle, so 1/100 gives a period of 0.01 seconds. The phase shift equation is ps = 360 * td / p, where ps is the phase shift in degrees, td is the time difference between waves and p is the wave period.

### How to find the phase shift of this cosine graph?

Again, $b$ could be negative but it is usually taken to be positive. An easy way to find the phase shift for a cosine curve is to look at the $x$ value of the maximum point. For cosine it is zero, but for your graph it is $3\\pi/2$. That is your phase shift (though you could also use $-3\\pi/2$).

### What does a negative phase shift on a sine curve mean?

the curve shifts from zero. 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

**How are amplitude, period, and phase shift related?**

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 Phase Shift is how far the function is shifted horizontally from the usual position.

**Which is an example of a positive phase shift C?**

In fact, a positive phase shift c actually indicates a shift to the left. Let’s look at some more examples: y = sin (x + 1) The sine curve shifted one unit to the left. y = sin (x + π/2) The curve shifted π/2 units to the left. Recall that π/2 is approximately 1.57.
