Write a sine function that has a midline of 2, an amplitude of 4 and a period of 11.

y = 4 sin (2π/11 x) + 2

Step-by-step explanation:

y = A sin (2π/T x + B) + C

where A is the amplitude,

T is the period,

B is the phase shift,

and C is the midline.

A = 4, T = 11, and C = 2. We'll assume B = 0.

y = 4 sin (2π/11 x) + 2
