# Complex Numbers: An Introduction

Siddharth V

This series ended on January 28, 2024. All 1:1 and group chats related to this series are disabled 7 days after the last session.

### Series Details

This series is designed for beginners in complex numbers who enjoy learning through doing and having discussions, and for learners who have already studied this topic but would like to refresh their knowledge and deepen their understanding. We will start by looking at the origins of the imaginary unit, and how we can do arithmetic with it, which leads us into the world of complex numbers. We will also look at how we can represent them geometrically, like we can with real numbers, as well as many other topics within complex numbers. Of course, a major reason why many learners dislike mathematics is because it seems as if what they are learning has no real life applications. We will, therefore, discuss some real life applications of complex numbers as a part of our sessions.

✋ ATTENDANCE POLICY

Please notify the tutor if you cannot attend a session, so that the tutor can provide you with the learning material for the session. If you miss 2 sessions in a row without notifying the tutor, you will be withdrawn from the series.

I'm a 14 year old in the UK with a strong passion for mathematics and computer science. While I am 14 years old, I am studying at a Year 13 (12th Grade) level in mathematics. I am joining Schoolhouse since I would like to help students in higher-level mathematics. I enjoy teaching very much - I tutor mathematics to students from disadvantaged socio-economic backgrounds in the UK and India.
