In linear algebra what is the dimension of zero vector? Determine the dimensions of the following subspace of \mathbf{R}^2 respectively \mathbf{R}^3: span\{ \begin{bmatrix} 0\0 \end{bmatrix} \} What is a free variable in linear algebra?
How to show that a basis is orthogonal? What is the meaning of "the decomposition is unique" in linear algebra? Find a basis for the subspace spanned by the given vectors. What is the dimension of the subspace? \vec v_1 = \begin {pmatrix} 1\\-1 \\-1\\3 \end {pmatrix}, \...
How does linear regression work in data analysis? Linear regression is a statistical technique used in data analysis to model the relationship between two variables. It assumes a linear relationship between the independent variable (input) and the dependent variable (output). The goal is to find ...
Yes, many scientific and graphing calculators support matrix calculations. You can add, subtract, multiply, and find determinants and inverses of matrices, which is useful in linear algebra and engineering applications. Can I use a calculator to solve algebraic equations?
all the participants were seasoned teachers of linear algebra. Johnson went on to declare his own ignorance regarding the right way to teach linear algebra, in spite of studying and teaching the subject for years. This was a sobering declaration from someone with his credentials. He is the co...
Given an arbitrary linear subspace V of M n ( K ) of codimension less than n - 1 , a classical result states that V generates the ( K ) -algebra M n ( K ) . Here, we strengthen this statement in three ways: we show that M n ( K ) is spanned by the products of the form...

Here is the fibring identity: Proposition 5 (Fibring identity) Let be a homomorphism. Then for any independent -valued random variables , one has The proof is of course in the blueprint, but given that it is a central pillar of the argument, I reproduce it here. Proof: Expanding ...
This is only optimal in the regime ; we expect to establish some eigenvalue repulsion, improving the RHS to for real matrices and for complex matrices, but this appears to be a more difficult task (possibly requiring some quadratic inverse Littlewood-Offord theory, rather than just linear ...
