Matrices Crash Course

This video covers the essentials for Unit 2 Topic 5 - Matrices for Specialist Maths. There's a lot in this video but there's a lot of connections to prior work throughout. I also suggest that your listen to me over your teachers at some point in this video when it comes to matrix multiplication so please don't tell them I said that :) Also said during explaining Matrix Multiplication that I'd go through why it's so weird but didn't end up doing it! There is a brief video coming up soon on this explicitly :) Timestamps: 0:00 - Introduction 1:00 - Idea Behind Matrices 2:22 - Essential Definitions 6:55 - Basic Operations 9:44 - Matrix Multiplication 21:13 - Determinant 24:53 - Inverse of a Matrix 31:28 - Matrix Algebra Definitions 36:35 - Extension Application Question 40:51 - Simultaneous Equations Using Matrices 44:55 - Bonus 3x3 Determinant (not Inverse lol)
