Find An Equation For The Sine Or Cosine Wave

When finding the equation for a trig function, try to identify if it is a sine or cosine graph.

To find the equation of sine waves given the graph:

  1. Observe the amplitude which is half the altitude between the maximum and minimum.
  2. Observe the menstruation of the function which is the horizontal distance for the function to echo. If the period is more than 2π then B is a fraction; use the formula period = 2π/B to find the exact value.
  3. Find whatever phase shift, h.

How To Decide The Equation Of A Sine And Cosine Graph?

The general equation of a sine graph is y = A sin(B(x - D)) + C
The full general equation of a cosine graph is y = A cos(B(x - D)) + C

Examples:
Given a transformed graph of sine or cosine, decide a possible equation.
