Essential Mathematics

• Credit value: 30 credits at Level 3
• Convenor and tutor: to be confirmed
• Assessment: coursework consisting of frequent short tests and problem-based homework (100%)

In this module we will reinforce your knowledge and ability with key mathematical techniques, so that you can enter Year 1 of the BSc programme with a very strong set of skills. The module will revise and extend crucial topics including algebra, functions, logarithms and basic differentiation.

Indicative syllabus

• Numbers and symbols: fractions, percentages and indexes and weighted average; arithmetic operations on fractions; parentheses in arithmetic expressions; surds; estimation of arithmetic expressions
• Algebra: evaluating algebraic expressions; rules of indices; collecting terms; expansion of brackets; factorizing; simplifying expressions involving rational functions; simplifying radicals; solving quadratics including parametrized equations; solving linear and quadratic inequalities including link with graphs solving simultaneous equations
• Logarithms: computing logs; manipulation of expressions involving logs; solving logarithmic equations; graphs of logarithmic and exponential functions
• Functions: notation of sets; using 'set builder notation'; definitions such as domain and range; evaluating functions including at parameters; graphing; relationship with graph; equations of lines
• Differentiation: derivative of polynomial functions and exponential functions; rules of differentiation; product, quotient and chain rules; idea of derivative as gradient of tangent; interpretation of the first and second derivatives; finding maxima and minima; applications to economics and business
