cool sounds!

a circle is an *example* of a sine wave. like a square is an *example* of linear functions. circles are made with sine waves...one vertical sine wave mixed with a horizontal sine wave creates circular motion

everything is sine waves....square waves are just lots of sine waves mixed in the appropriate way

linear functions have a constant rate of accelration.......sine functions (sine waves) do not, they do have limits though like linear functions (triangle waves).....-1 and 1......
