Let us put a circle of radius 5 on a graph: Now let's work out exactlywhere all the points are. We make a right-angled triangle: And then use Pythagoras: x2 + y2 = 52 There are an infinitenumber of those points, here are some examples: In all cases a point on the circle follows the rule x2 + y2 = radius2 We can use … See more Now let us put the center at (a,b) So the circle is all the points (x,y) that are "r" away from the center (a,b). Now lets work out where the points are (using a right-angled triangle and … See more But you may see a circle equation and not know it! Because it may not be in the neat "Standard Form" above. As an example, let us put some values to a, b and r and then expand it And … See more 1. Plot the center (a,b) 2. Plot 4 points "radius" away from the center in the up, down, left and right direction 3. Sketch it in! See more Now imagine we have an equation in General Form: x2 + y2+ Ax + By + C = 0 How can we get it into Standard Formlike this? (x−a)2 + (y−b)2 = r2 The answer is to Complete the Square … See more WebImagine there are n ≥ 3 circles surrounding your unit circle. Then the situation would look like: Whence cos ( x) = r r + 1. The angle x is half of the interior angle of the corresponding regular polygon, so x = n − 2 2 n ⋅ 180 ∘. You can then solve for r = cos ( x) 1 − cos ( x). For example. when n = 4 we have r = cos.
