This module introduces several important mathematical constructions, namely, complex numbers, vectors and matrices, and shows how they are employed in various areas of mathematics and statistics. **For students outside of the Department, an appropriate A level in Mathematics (or equivalent) is required for this module. If you are unsure whether you meet this criteria please contact maths@essex.ac.uk before attempting to enrol.**
This module is taught to first year students on a number of degrees and introduces mathematical constructions which are used in a wide range of applications of mathematics, namely, complex numbers, vectors and matrices.
On completion of this module students should be able to:
- understand the geometric and algebraic properties of vectors in two- and three-dimensional Euclidean space;
- perform simple operations on matrices;
- solve systems of linear equations using row operations;
- calculate the determinant and the inverse of a matrix;
- calculate the eigenvalues and eigenvectors of a matrix;
- diagonalize a symmetric matrix;
- be able to add, subtract, multiply, and divide complex numbers in Cartesian form;
- be able to plot complex numbers on an Argand diagram;
- be able to move between Cartesian and polar forms of complex numbers;
- be able to calculate arguments, moduli and complex conjugates;
- be able to multiply and divide complex numbers in polar form;
- be able to find complex nth roots.
Syllabus
Complex numbers:
- addition, subtraction, multiplication and division of complex numbers in both Cartesian and polar form
- de Moivre's theorem
- complex nth roots
Vectors:
- Geometry and algebra of vectors in 2 & 3 dimensions
- vector addition and scalar multiplication
Matrices:
- matrix addition and multiplication
- systems of linear equations
- Gaussian elimination, elementary row operations
- identity and inverse matrices, determinants;
- eigenvalues and eigenvectors
- diagonalization of symmetric matrices
- applications to quadratic forms in two and three dimensions
Teaching will be delivered in a way that blends face-to-face classes, for those students that can be present on campus, with a range of online lectures, teaching, learning and collaborative support.
This module does not appear to have a published bibliography for this year.

Exam format definitions
- Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
- In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
- In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
- In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary,
for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.
Your department will provide further guidance before your exams.

be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements,
industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist
of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules.
The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
