That would be a continuous disaster for Doron, an example of which follows:So, say what you like, but it would be nice if Doron would at least adopt the conventional vocabulary and attempt to communicate rationally instead of obfuscate then hide behind his "you can't get it" shield.
According to Doronetics, X and Y are the coordinates of the circle's center.The equation of a circle is X2 + Y2 = R2, where X,Y is the circle's center coordinate and R is the size of the circle's radius.
There is naturally the other option that treats X as the independent and Y as the dependent variables:
X2 + Y2 = R2
Y2 = R2 - X2
Y = f(x) = SQR(R2 - X2)
The function simply draws a semicircle. The equation for a full circle is given by the implicit form, coz there are actually two functions employed to draw a full circle. (Cartesian coordinates.)
But Doron has a different mission for X and Y. It's a monument to his total ignorance of anything which is even slightly scented with rationality and high school math, as "prophesied" in the OP.
BUT....! Considering the circle equation from the grossly_crossly_context_dependency_locality_spacial_glacial_only prospect, X and Y are indeed the coordinates of the circle's center and also are the coordinates of the centroid of every galactic dust. But only top thinkers can comprehend that.
