The circle could've been done in one equation

[–] [email protected] 37 points 10 months ago (1 children)

One equation, sure, but not in one valid function (without making it parametric anyways)

x^2^+y^2^=1
or, in this case
(x-2)^2^+(y-2)^2^=1

Not valid functions

A valid function needs to pass the vertical line test

[–] [email protected] 2 points 10 months ago

Ok you're right

[–] [email protected] 3 points 10 months ago

A that's a single equation alright. But as the previous poster pointed out, it's not a function.
