Constructions which help me answer questions from an outline course in Acoustics. I would love to hear back if any of this material is useful to you.

Lissajous 2: the Locus of the motion

A more elegant solution to the question ...Two periodic motions are propagated in perpendicular directions from the same source. What is the resultant motion?...

...is to find the locus of points which describe the motion. The Locus[] command at work.
