Syllabus
This course develops basic mathematical methods and will emphasise their applications to problems in economics, management and related areas.
Basics:
Basic algebra; Sets, functions and graphs; Factorisation (including cubics); Inverse and composite functions; Exponential and logarithm functions; Trigonometrical functions
Differentiation:
The meaning of the derivative; Standard derivatives; Product rule, quotient rule and chain rule; Optimisation ; Curve sketching; Economic applications of the derivative: marginals and profit maximisation
Integration:
Indefinite integrals; Definite integrals; Standard integrals; Substitution method; Integration by parts; Partial fractions; Economic applications of integration: determination of total cost from marginal cost, and cumulative changes
Functions of several variables:
Partial differentiation; Implicit partial differentiation; Critical points and their natures; Optimisation; Economic applications of optimisation; Constrained optimisation and the Lagrange multiplier method; The meaning of the Lagrange multiplier; Economic applications of constrained optimisation
Matrices and linear equations:
Vectors and matrices, and their algebra; Systems of linear equations and their expression in matrix form; Solving systems of linear equations using row operations (in the case where there is a unique solution); Some economic/managerial applications of linear equations
Sequences and series:
Arithmetic and Geometric Progressions; Some Financial application of sequences and series.
