An Ellipsis Sine Wave is a Sine Wave that is not fully connected; Ellipsis Sine Waves are also considered "Dotted Sine Waves" or "Dashed Sine Waves" they're like dotted lines except that it goes in a similar pattern as a sine wave. Real Ellipsis Sine Waves start large and then slowly decline exponentially slowing down. If you to the end of an infinitely large sine wave, at the end it would no longer be an Ellipsis Sine Wave.
In class, I drew an ellipsis sine wave so I wouldn't mistake it for the sine waves I had to solve for my homework.
