Identities and choosing a method

Identities and choosing a method

Flowchart showing how to choose a partial fraction form by checking whether a fraction is proper, whether factors are distinct or repeated, and when to add a polynomial part

Algebraic methods often turn one expression into another form that is easier to use. A key idea is an identity, written with ≡\equiv≡, which is true for every allowed value of xxx, so you can compare coefficients or substitute convenient values.

Step-by-step lessons covering Edexcel A Level Maths Algebraic Methods for A Level Maths. Each lesson breaks down 1.1 Proof by Contradiction, 1.2 Algebraic Fractions, 1.3 Partial Fractions, 1.4 Repeated Factors, and 1.5 Algebraic Division, then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
