OCR • Mathematics

Easy to read and in detailed notes, that include worked through examples. Specific for OCR Mei A-level maths year 2. Covers: by parts, by substitution, integrating trig, integrating expos and logs, partial fractions and further Integration.

Document contains four methods of proofs used at AS Level - proof by exhaustion, proof by deduction, proof by counter example and consequence & equivalence. It is a summary and includes exam styled questions and solutions below the questions as well as examples throughout and other key points created by myself.

Explains with examples: Proof by exhaustion Proof by deduction

Explains with examples: Disproof by counter - examples Proof by contradiction

OCR A Level Math Exam Questions and Mark Scheme 1. i. The first three terms of an arithmetic progression are 2x, x + 4 and 2x − 7 respectively. Find the value of x. [3] ii. The first three terms of another sequence are also 2x, x + 4 and 2x − 7 respectively. a. Verify that when x = 8 the terms form a geometric progression and find the sum to infinity in this case. [4] b. Find the other possible value of x that also gives a geometric progression. [4] 2. Sarah is carrying out a seri...
