For a system of equations {ax+by=jcx+dy=k ,the coefficient matrix is [abcd] and the augmented matrix is [abjcdk]
a) For the system {8x+3y=253x9y=12a=8,b=3,c=3 and d=9 so the coefficient matrix is [8339]
b) For the system {8x+3y=253x9y=12a=8,b=3,c=3,d=9,j=25 and k=12 so the augmented matrix is [83253912]

Let λ1,λ2,λ3,bR with λ10. Show that the linear equation λ1x1+λ2x2+λ3x3=b has a set of solutions of the form {v}+span(v1,v2), with v,v1,v2R3 and v1,v2 are linearly independent.
Could you give me a hint how we could show that, since I have no idea? I don't really know how to start.

Quick way to check if a matrix is diagonalizable.
Is there any quick way to check whether a matrix is diagonalizable or not?
In exam if a question is asked like "Which of the following matrix is diagonalizable?" and four options are given then how can one check it quickly? I hope my question makes sense.

I found that studying linear algebra by getting into vector spaces and linear transformations first made things very easy. This is the approach Halmos or Axler, just to name a few, take.
IMHO, the alternative of going through solving systems of linear equations beforehand, obscures the topic.
What would be equivalent, slightly abstract approaches to study analysis for a freshman? A bit of topology and metric spaces, like Rudin? Multivariate calculus with differential forms, like Hubbard & Hubbard?

I am a computer science research student working in application of Machine Learning to solve Computer Vision problems.
Since, lot of linear algebra(eigenvalues, SVD etc.) comes up when reading Machine Learning/Vision literature, I decided to take a linear algebra course this semester.
Much to my surprise, the course didn't look at all like Gilbert Strang's Applied Linear algebra(on OCW) I had started taking earlier. The course textbook is Linear Algebra by Hoffman and Kunze. We started with concepts of Abstract algebra like groups, fields, rings, isomorphism, quotient groups etc. And then moved on to study "theoretical" linear algebra over finite fields, where we cover proofs for important theorms/lemmas in the following topics:
Vector spaces, linear span, linear independence, existence of basis. Linear transformations. Solutions of linear equations, row reduced echelon form, complete echelon form,rank. Minimal polynomial of a linear transformation. Jordan canonical form. Determinants. Characteristic polynomial, eigenvalues and eigenvectors. Inner product space. Gram Schmidt orthogonalization. Unitary and Hermitian transformations. Diagonalization of Hermitian transformations.
I wanted to understand if there is any significance/application of understanding these proofs in machine learning/computer vision research or should I be better off focusing on the applied Linear Algebra?
