Determinant Of A Square Matrix Of Order 2
>> Determinants are like matrices, but done up in absolute-value bars instead of square brackets. There is a lot that you can do with (and learn from) determinants, but you’ll need to wait for an advanced course to learn about them. In this lesson, I’ll just show you how to compute 2×2 and
>> If you have a square matrix, its determinant is written by taking the same grid of numbers and putting them inside absolute-value bars instead of square brackets
>> Just as absolute values can be evaluated and simplified to get a single number, so can determinants. The process for evaluating determinants is pretty messy, so let’s start simple, with the 2×2 case.
