Desmos does plot circle when I enter:
But when I enter:
It doesn't plot anything.
This problem does not exist with explicit functions, e.g. when I enter:
That is the same as:
Desmos does plot some cubic function.
So I can conveniently plot any explicit function without repetitions of code and typing, but not implicit functions.
Why? Does exist work around to achieve the same goal/aim/purpose also with implicit functions too?
