Mathematics: The Secret of Imaginary Numbers With Dr Wahiba Toubal From Bishop Grosseteste University

June 16 @ 11:15 - 12:15



In this interactive session we will explore complex numbers algebraically and geometrically and their application in real life.

We will cover:

  • Algebraic and geometric manipulations with complex numbers
  • Introduction to fractals and the Mandelbrot set
  • Applications of complex numbers in the real world

The session will support KS5 students by helping them to:

  • Perform algebraic manipulations with complex numbers
  • Understand the geometric manipulation of complex numbers
  • Explore fractals and the Mandelbrot set
  • Apply complex numbers to the real world

Students will need pen/paper/scientific calculator to gain the most from the session (Please see Preparation/Pre-reading below).



Our events are designed so that a group of students can take part from a classroom or students and teachers can take part as individuals, either from school or from home. This means that sessions will continue irrespective of possible school closures.

As a live, participative event, this session will not be recorded but slides and other resources will be shared after the event, where available.


Suitable for: Year 12 and 13 students (and equivalent) studying, or interested in studying, Maths and related subjects. We also welcome interested students from other disciplines.

Preparation/Pre-Reading: Students may wish to consider questions they have about the topic and/or about studying this discipline at university.

  • Students need to review different ways to solve quadratic functions of the type ax^2+bx+c=0
  • Students need to review plotting two dimensional numbers with x and y coordinates. For example, plotting point A with coordinates (1, -2).
  • Desirable: review basic differentiation and integration methods for simple functions.

Students will need pen/paper/scientific calculator to gain the most from the session.

The IT Setup: The event will be run on Bluejeans and participants will be able to join using laptops, tablets, and mobile devices. If you are joining as a school group, we recommend connecting with one device and projecting on to a whiteboard. You will be able to interact with the university via a microphone and/or typed comments and questions. Full details will be sent to those who have registered (see below) prior to the event.

Booking a Place: This is free for schools and colleges. If you would like to take part in this event, please register your interest using the link to the registration form below:
