The formulas become a bit more managable with the definitions of the angular frequency ω and the wave number k, given by

ω = 2π/T      and      k = 2π/λ


We obtain then for the two disturbances the following expressions

u1(x,t) = A1sin(ω1t-k1x+φ1)

     and     

u2(x,t) = A2sin(ω2t-k2x+φ2)


Hence, the total disturbance of the floaters is described by

u(x,t) = A1sin(ω1t-k1x+φ1) + A2sin(ω2t-k2x+φ2)
