We say that 2 vectors are orthogonal if they are perpendicular to each other. Proposition An orthogonal set of non-zero vectors is linearly independent.
Given a set of vectors you can determine if they are linearly independent by writing the vectors as the columns of the matrix A

vector addition the check is also straightforward. 1.3 Definition A subset of a vector space is linearly independent if none.
We have three solution vectors and for a complete solution these vectors must be linearly independent
A vector b is in the span of the columns of a matrix A if and only if the equation Ax = b is A set of 3 vectors in R4 is always linearly independent.
Let V be a vector space. A linearly independent spanning set for V is called a basis. Equivalently a subset S ? V is a basis for V if any.
