Aims

The course unit unit aims to provide an introduction to the basic elements of calculus.

Overview

This lecture course introduces the basic ideas of complex numbers relating them the standard transcendental functions of calculus. The basic ideas of the differential and integral calculus are revised and developed. Vectors in two and three dimensions are introduced and this leads on to the calculus of functions of more than one variable and the beginnings of vector calculus.

Learning outcomes

On successful completion of this module students will be able to: 

  • Represent complex numbers in the complex plane and use them to relate trigonometric and exponential functions.  
  • Sketch polynomial, rational, inverse and some standard functions of a single variable in Cartesian and polar coordinates.
  • Evaluate and interpret limits and derivatives of algebraic functions, including functions expressed in implicit or parametric form.
  • Select and deploy methods for evaluating integrals of functions of a single variable.
  • Construct and manipulate Taylor series of scalar functions of one and two variables.
  • Manipulate vectors using tools such as scalar and vector products, deploying these quantities to solve geometric problems.
  • Construct, deploy and interpret derivatives of scalar functions of more than one variable.
  • Construct, evaluate and interpret simple integrals of functions of two variables, using tools such as the Jacobian and Green's theorem. Construct and evaluate line integrals.
  • Locate and classify extrema of functions of two variables.

  • Integration. Definite and indefinite integrals; Fundamental Theorem of Calculus; techniques: linearity, integration by parts, partial fractions, substitution; lengths of curves, surfaces and volumes of revolution.
  • Vectors in 2 and 3 Dimensions. Representation as directed line segments (magnitude, direction); choice of axes, components, Cartesian representation; basic properties, addition, subtraction, polar representation and relationship with complex numbers in 2 dimensions; scalar and vector product; representation of lines, planes, curves and surfaces.
  • Functions of more than One Variable. Partial derivative, chain-rule, Taylor expansion; turning points (maxima, minima, saddle-points); grad, div and curl and some useful identities in vector calculus; integration in the plane, change of order of integration; Jacobians and change of variable; line integrals in the plane; path-dependence, path independence; Stokes' theorem and Green's theorem.

Recommended reading

The course is based on the following text:

James Stewart, Calculus, Early Transcendentals, International Student Edition, Thomson (any recent edition).

Feedback methods

Feedback seminars will provide an opportunity for students' work to be discussed and provide feedback on their understanding.  Coursework or in-class tests (where applicable) also provide an opportunity for students to receive feedback.  Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.

Study hours
