**Unit C2: Core Mathematics 2**

**AS compulsory unit for GCE AS and GCE Mathematics, GCE AS and GCE Pure Mathematics**

Module 1 | Algebra and functions - Edexcel Core Maths 2 (49:32 mins) | |
---|---|---|

Simple algebraic division; use of the Factor Theorem and the Remainder Theorem. Only division by \((x + a)\) or \((x – a)\) will be required. Students should know that if \(f(x) = 0\) when \(x = a\), then \((x – a)\) is a factor of \(f(x)\). Students may be required to factorise cubic expressions such as \(x^3 + 3x^2 – 4\) and \(6x^3 + 11x^2 – x – 6\). Students should be familiar with the terms 'quotient' and 'remainder' and be able to determine the remainder when the polynomial \(f(x)\) is divided by \((ax + b)\). | ||

Module 2 | Coordinate geometry - Edexcel Core Maths 2 (70:25 mins) | |

Coordinate geometry of the circle using the equation of a circle in the form \((x – a)^2 + (y – b)^2 = r^2\) 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. Students should be able to find the radius and the coordinates of the centre of the circle given the equation of the circle, and vice versa. | ||

Module 4 | Trigonometry - Edexcel Core Maths 2 (114:24 mins) | |

The sine and cosine rules, and the area of a triangle in the form \(\dfrac{1}{2} ab \sin C\). Radian measure, including use for arc length and area of sector. Use of the formulae \(s = r\theta\) and \(A = \dfrac{1}{2} r^2 \theta\) for a circle. Sine, cosine and tangent functions. Their graphs, symmetries and periodicity. Knowledge of graphs of curves with equations such as \(y = 3 \sin x, y = \sin \left( x + \dfrac{\pi}{6} \right), y = \sin 2x\) is expected. Knowledge and use of \(\tan \theta = \dfrac{\sin \theta}{\cos \theta}\), and \(\sin^2 \theta + \cos^2 \theta = 1\). Solution of simple trigonometric equations in a given interval. Students should be able to solve equations such as \(\sin \left( x + \dfrac{\pi}{2} \right) = \dfrac{3}{4}\) for \(0 < x < 2\pi\), \(\cos (x + 30^{\circ}) = \dfrac{1}{2}\) for \(-180^{\circ} < x < 180^{\circ}\), \(\tan 2x = 1\) for \(90^{\circ} < x < 270^{\circ}\), \(6 \cos^2 x + \sin x - 5 = 0, 0^{\circ} \leq x < 360\), \(\sin^2 \left( x + \dfrac{\pi}{6} \right) = \dfrac{1}{2}\) for \(-\pi \leq x < \pi\). | ||

Module 7 | Integration - Edexcel Core Maths 2 (63.02 mins) | |

Evaluation of definite integrals. Interpretation of the definite integral as the area under a curve. Students will be expected to be able to evaluate the area of a region bounded by a curve and given straight lines. Eg find the finite area bounded by the curve \(y = 6x - x^2\) and the line \(y = 2x\). \(\displaystyle\int x dy\) will not be required. Approximation of area under a curve using the trapezium rule. For example, evaluate \(\displaystyle\int_{0}^{1} \surd (2 x + 1) dx\) using the values of \(\surd (2x + 1)\) at | ||
