To make sure our students, who come from all over the world, are up to speed for the challenges ahead, this lecture recaps much of the work they should have done at high school, providing a short description of some of the basics of complex numbers.
But even in an recap there are subtle differences and pointers to what's to come.

All first and second year lectures are followed by tutorials where students meet their tutor in pairs to go through the lecture and associated problem sheet and to talk and think more about the maths. Third and fourth year lectures are followed by classes.
