MATH CALCULATOR
Phase Shift Calculator
Easily calculate phase shifts in trigonometric functions for precise adjustments.
What is the Phase Shift Calculator & How does it work?
A phase shift in a trigonometric function is the horizontal displacement of the graph from its standard position. For a sine or cosine function, the general form is ( y = A sin(Bx – C) + D ), where ( C/B ) represents the phase shift.
The phase shift affects when the function reaches its maximum and minimum values. A positive phase shift moves the graph to the right, while a negative phase shift moves it to the left.
The phase shift affects when the function reaches its maximum and minimum values. A positive phase shift moves the graph to the right, while a negative phase shift moves it to the left.

Frequently Asked Questions
What is phase shift in trigonometric functions?
Phase shift is the horizontal displacement of a trigonometric function’s graph from its standard position, affecting when it reaches maxima and minima.
How do I calculate the phase shift for a sine or cosine function?
To calculate the phase shift, divide the constant C by the coefficient B in the general form of the function y = A sin(Bx – C) + D.
Does a positive phase shift move the graph to the left or right?
A positive phase shift moves the graph to the right, while a negative phase shift moves it to the left.
What does the phase shift tell us about the function?
The phase shift indicates when the function reaches its maximum and minimum values relative to its standard position.
Can you explain how frequency affects the phase shift calculation?
Frequency, represented by B in the function, affects the phase shift calculation. A higher frequency compresses the graph horizontally, while a lower frequency stretches it.
How does changing the amplitude affect the phase shift?
Changing the amplitude (A) does not affect the phase shift; it only changes the height of the function’s peaks and troughs.
What is the formula for calculating phase shift in a trigonometric function?
The formula for calculating phase shift is C/B, where C is the horizontal shift and B is the frequency factor in the general form y = A sin(Bx – C) + D.
