What exactly does linear dependence and linear independence imply ...
I have a very hard time remembering which is which between linear independence and linear dependence... that is, if I am asked to specify whether a set of vectors are linearly dependent or …
How to Tell If Matrices Are Linearly Independent
If I have two matrices, for example: (1 0 2 1) and (1 2 4 3), how do I determine if they are linearly independent or not in R4? I am familiar with checking for independence with vectors, such as by …
linear algebra - Expanding a linearly independent set to a basis ...
Mar 17, 2016 · 1 I assume the easiest way to expand these vectors to a basis would be to check which two basis vectors are linearly independent with the two you already have, and add them. By …
Why is the determinant zero iff the column vectors are linearly …
The reason is that a matrix whose column vectors are linearly dependent will have a zero row show up in its reduced row echelon form, which means that a parameter in the system can be of any value …
What does it mean when we say a variable changes linearly?
Aug 4, 2021 · I have attached a screenshot in which a variable is defined for an object somehow that it linearly decreases from 500 micrometers at the top of the object to 50 micrometers at the bottom of …

linear algebra - Determine if vectors are linearly independent ...
12 you can take the vectors to form a matrix and check its determinant. If the determinant is non zero, then the vectors are linearly independent. Otherwise, they are linearly dependent.
Proof that columns of an invertible matrix are linearly independent
1 we want to proove that A is invertible if the column vectors of A are linearly independent. we know that if A is invertible than rref of A is an identity matrix so the row vectors of A are linearly independent.
Why is it called linearly independent? - Mathematics Stack Exchange
Sep 5, 2015 · To me linearly independence is one of those math definitions that it is easier to get the feeling with characterisations (in this case something that isn't linearly dependent), rather than …
