### C2 Topic List

 1 Algebra and functions Simple algebraic division Use of the Factor Theorem and the Remainder Theorem. Knowledge that if f(x) = 0 when x = a, then (x – a) is a factor of f(x). 2 Coordinate geometry in the (x, y) plane Coordinate geometry of the circle using the equation of a circle in the form (x – a)2 + (y – b)2 = r2 and including use of the following circle properties: (i) the angle in a semicircle is a right angle; (ii) the perpendicular from the centre to a chord bisects the chord; (iii) the perpendicularity of radius and tangent. 3 Sequences and series The sum of a finite geometric series; the sum to infinity of a convergent geometric series, including the use of |r| < 1.
