the shape of the figure until a known figure of a specific ratio will be obtained‚ and these ratios will be used to determine the unknown variables. Lissajous figures are plane curves represented by: x = Axcos(ωxt + Øx) y = Aycos(ωyt + Øy) Where: Ax & Ay – amplitudes; t – time; ω - angular velocity; Ø – phase difference When the amplitudes‚ frequencies‚ and phases of the two waves differ‚ complicated intermeshing curves are produced. There are however a few special cases which occur: 1
