## Frequently asked questions about DR.Lissajous

### What is DR.Lissajous?

DR.Lissajous is an educational application that allows users to create and explore Lissajous curves by simulating the horizontal and vertical motion of an electron beam on an oscilloscope. You can change parameters like amplitude, frequency, and phase difference to see how the curves change.

### How does DR.Lissajous work?

The app simulates the combination of two perpendicular simple harmonic motions. By adjusting the amplitudes, frequencies, and phase difference of these motions, users can generate a wide variety of complex and visually interesting Lissajous figures.

### What can I do with DR.Lissajous?

You can create Lissajous curves by tapping the screen, which generates a spirograph-like representation. You can then experiment with changing the amplitudes, frequencies, and phase differences to observe how these modifications affect the resulting curve.

### Is DR.Lissajous suitable for learning?

Yes, DR.Lissajous is an excellent tool for understanding wave interference, oscillation, and the mathematical principles behind Lissajous curves. Its visual nature makes abstract concepts more tangible for learners.

### What devices does DR.Lissajous support?
