In an equation like this: y = acos(bx + c)
The value of a is the amplitude. For this problem the amplitude is 3.
The value of b determines the period using this equation: Period = 2π/b = 360°/b
For this problem, the period of cos is 2π/1 = 2π or 360°.
The value of c determines the horizontal shift.
