The video covers FP2 Chapter 3 on complex numbers, building on Year 1 concepts. It delves into different representations on the Argan diagram, exploring transformations of the complex plane. The video includes a recap of Year 1 loci, introduces new FP2 concepts, and demonstrates solving loci problems algebraically. It also provides a geometric interpretation of loci and includes a practice problem to reinforce learning.
