These are the statements describing what students need to learn:
- understand and use the equation of a straight line, including the forms y – y1 = m(x – x1) and ax + by + c = 0; Gradient conditions for two straight lines to be parallel or perpendicular. Be able to use straight line models in a variety of contexts
- understand and use the coordinate geometry of the circle including using the equation of a circle in the form (x – a)2 + (y – b)2 = r2 Completing the square to find the centre and radius of a circle; use of the following properties: the angle in a semicircle is a right angle, the perpendicular from the centre to a chord bisects the chord, the radius of a circle at a given point on its circumference is perpendicular to the tangent to the circle at that point
- understand and use the parametric equations of curves and conversion between Cartesian and parametric forms
- use parametric equations in modelling in a variety of contexts
