where is the pie symbol? Youcannot form a circle without the 3.14.

A circle is the set of points that are all at some fixed distance from the center. In the case of the equation above the center is the origin - the point (0,0). Now the definition of distance between two points p= (px,py) and q = (qx,qy) is
d = sqrt( (qx-px)^2 + (qy-py)^2).
If you plug the origin into that, and used the square of the distance, then you can see that the equation represents all those points at a distance r from the origin, which is a circle.

This comes into play later on when you fiddle with the "unit circle" which has a lot to do about cosines and sines.
Pi is inherent in the equation. If you fiddle with the values you can deduce Pi from them.

That sounds like a squared + b squared = c squared which i think is the pythagorem theorey or something fancy like that. Like its a triangle formula, not a cirlcle formula.

Simplistically, it forms the hypotenuse of a triangle. Do a simple rotation on the hypotenuse and you have a circle.

Just chart it out, and you will see it does form a circle.

there is probably a really complicated proof, but if you plot the points, you'll see it is a circle, dont know why that guy was rambling about pi
