    Oscillatory motion of a spring-mass system

    Woops, that was a typo...thanks for pointing that out lzkelly. I did mean to use a different variable, like Y=Acos(kx-wt).. So do you mean...I can take the wavenumber k=2pi/lambda, which would be it's spatial component or I can take k=2pi/T? i.e. k is then angular frequency?
