xy=a(b sin px + c cos qy) https://www.desmos.com/calculator/q40z2te82s
For no other reason than why not. Go beyond functions that must have an application in today's 'real world' and take a play before getting down to the standard functions on the curriculum.
It's even better if you make it xy=a(sin x + cos y) and add a slider for a. Then the loop pops unexpectedly into existence around a=6.241
(I wondered if it might be a=2π, but nothing so sensible)
