## How do you find the phase shift of a trig function?

In our case, the phase shift formula gives: A * sin(Bx – C) + D = A * sin(B * (x – C/B)) + D , which is a phase shift of C/B (to the right) of the function A * sin(Bx) . Of course, we can repeat the above for the cosine as well.

How do you find the amplitude of a trig function?

The amplitude of a trigonometric function is half the distance from the highest point of the curve to the bottom point of the curve: (Amplitude) = (Maximum) – (minimum) 2 .

What is the formula for period in trig?

We may also calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin(Bx + C) and y = A cos(Bx + C) is 2π/|B| radians. Frequency is defined as the number of cycles completed in one second.

### 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 period and amplitude of trig functions?

Every sine function has an amplitude and a period. Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat.

Is phase shift the same as horizontal shift?

horizontal shift and phase shift: If the horizontal shift is positive, the shifting moves to the right. While this distinction exists for physicists and engineers, some mathematics textbooks use the terms “horizontal shift” and “phase shift” to mean the same thing. …

## What is amplitude in trig?

The amplitude of a function is the amount by which the graph of the function travels above and below its midline. When graphing a sine function, the value of the amplitude is equivalent to the value of the coefficient of the sine. The amplitude is dictated by the coefficient of the trigonometric function.

What is the amplitude period Phase Shift and vertical shift?

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 horizontally to the right of the usual position. The Vertical Shift is how far the function is vertically up from the usual position.
