Write a sine function that has an amplitude of 4, a midline of y, equals, 2y=2 and a period of 22.

The general form of a sine function is y = A*sin(B(x - C)) + D, where:

• A is the amplitude
• B is the frequency, which is related to the period (P) by the formula B = 2π/P
• C is the phase shift (how much the graph is shifted horizontally)
• D is the vertical shift, which is the midline of the function

Given that the amplitude is 4, the midline is y = 2 (so D = 2), and the period is 22, we can substitute these values into the general form to get the specific function.

First, we need to find B. Since the period P is 22, B = 2π/P = 2π/22 = π/11.

Since there's no information about a phase shift, we'll assume C = 0.

So, the specific sine function that meets the given conditions is:

y = 4*sin((π/11)x) + 2
