The geometry of a circle. mc-TY-circles-2009-1. In this unit we find the equation of a circle, when we are told its centre and its radius. There are two different forms of the equation, and you should be able to recognise both of them. We also look at some problems involving tangents to circles.
Math Formulas: Circle. Equation of a circle. In an x y coordinate system, the circle with center (a; b) and radius r is the set of all points (x; y) such that: 1. (x a)2 + (y b)2 = r2. Circle centered at the origin: 2. x2 + y2 = r2. Parametric equations. 3. where t is a parametric variable. = a + r cos t. = b + r sin t.
Circles Introduction. Notes, examples, formulas, and practice questions. Topics include parts of a circle, arc length, sector area, and more.
