Lissajous Figures

Making Lissajous's Figures is a teadous process when we start from tracing the sine curves and making the superposition. It was very difficuilt for me too. Then I realised I had programming power. So I made this program.

What are Lissajous's Figures?

When two perpendicular simpoer harmonic motions superimpose, they make some beautiful images and it is called Lissajous's Figures.

Genral equation for Lissajous's Figures is given by

$$\frac{x^2}{a^2}+\frac{y^2}{b^2}+\frac{2xy}{ab}\cos\delta=\sin^2\delta$$

How to draw them?

In this program I have plotted the first SHM on x axis and the other SHM on y axis. $$x=a\sin(t\omega_1)$$ $$y=b\sin(t\omega_2+\delta)$$

I have gievn sliders to control

1. the phase differace delta
2. The ratio of frequencies w1/w2
3. The Ratio of amplitudes
