Transposes and Inverses II | Linear Algebra MATH1141 | N J Wildberger
We introduce the notion of the inverse of an n by n matrix. Concrete formulas for the 1 by 1 and the 2 by 2 cases are given, and we derive various useful properties. ************************ Screenshot PDFs for my videos are available at the website http://wildegg.com. These give you a co

Advice for Research Mathematics | Compositional Inverses for polyseries | Wild Egg Maths
We discuss the role of composition and compositional inverses in the world of polyseries. Composition is an important kind of additional operation that is available for polynumbers, and the notion of a compositional inverse becomes available once we move further into polyseries. There i

Invertible matrices and systems of linear equations I | Linear Algebra MATH1141 | N J Wildberger
We tackle the close connection between taking the inverse of a matrix and solving a system of linear equations. We meet again the question: if a square n by n matrix has a right inverse, is it invertible? Along the way, we discover how to find the inverse of an n by n invertible matrix by

Invertible matrices and systems of linear equations II | Linear Algebra MATH1141 | N J Wildberger
We continue showing that an n by n matrix is invertible precisely when the equation Ax=b has a unique solution for any b. Along the way we will need to look at the matrix formulation of elementary row operations, and how these elementary matrices are invertible. This is a rather subtle but

An identity matrix under matrix multiplication serves a similar role to the number 1, when it comes to integer multiplication, i.e. any number times 1, remains that number. You can learn more about Mathematica on my Udemy course at https://www.udemy.com/mathematica/ PS! Wait until Udemy
