Standard form of a circle

Coordinate diagram of a circle with centre C(a,b), point P(x,y), radius r, and the standard equation labelled A circle is the set of all points a fixed distance from one centre. If the centre is (a,b)(a,b)(a,b) and the radius is rrr, then

Step-by-step lessons covering Edexcel AS Level Maths Circles for AS Level Maths. Each lesson breaks down 6.1 Midpoints and Perpendicular Bisectors, 6.2 Equation of a Circle, 6.3 Intersections of Straight Lines and Circles, 6.4 Use Tangent and Chord Properties, and 6.5 Circles and Triangles, then works through exam-style questions in Paper 1 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
