**Reiny**, Monday, January 10, 2011 at 7:02pmThe only actual calculation you have to do deals witht the period.

period = 2π/k

3π/7 = 2π/k

k =

I am also not clear about your information re phase shift,

I will assume that by " a phase shift of -π/5" you mean a shift of π/5 to the left.

If you meant the opposite, just change the sign for the phase shift in my answer.

y = cos(14/3)(Ø + π/5) - 2
