The cosine function with amplitude 2 and period 6π is given by:

y = 2cos(x/3).

What is the standard cosine function?

The standard cosine function is given by:

y = Acos(Bx).

In which:

  • The amplitude is A.
  • The period is of 2pi/B.

For a cosine function with amplitude 2 and period 6π, we have that A = 2 and B = 1/3, hence:

y = 2cos(x/3).
