Before embarking on our study of the elementary properties of vector spaces and their linear subspaces in the succeeding chapters, let us collect a list of examples of vector spaces. Of basic importance are the
Modern linear algebra considers these same objects in the abstract setting of vector spaces. Before diving into vector spaces, here is an example of a linear combination of two vectors: 5⟨2,1⟩+3⟨7,−3⟩=⟨31,−4⟩.
Understand the motivation behind the vector space axioms. Discover properties of abstract vector spaces. Learn about vector spaces through theory...
Linear AlgebraVectorsFind the Direction Angle of the Vectory=−5i+2jy=-5i+2j Apply the direction angle formula θ=arctan(ba)θ=arctan(ba) where a=−5a=-5 and b=2b=2. θ=arctan(2−5)θ=arctan(2-5) Solve for θθ. Tap for more steps... θ=−0.38050637θ=-0.38050637...
We have a series of linear algebra lectures given in videos by Khan Academy. In this series, we will learn matrices, vectors, vector spaces, determinants and transformations. Introduction to matrices Matrix multiplication Inverting Matrices (part 1) Inverting Matrices (parts 2 & 3) Matrices to...
Linear Algebra Explore and compute properties of vectors, matrices and vector spaces. Compute properties of a vector: vector <3, -4> Calculate properties of a matrix: {{6, -7}, {0, 3}} Determine whether a set of vectors is linearly independent: Are (2, -1) and (4, 2) ...
The various types of algebra are elementary algebra, abstract algebra,linear algebra, boolean algebra, and universal algebra. What is Abstract Algebra? Abstract algebra, or modern algebra is the study of algebraic structures including groups, rings, fields, modules, vector spaces, lattices, and alge...

vector. The green curve implicates an approximation of the spatial curve at pointt_{0} { = }\frac{\pi }{{{10}}}. The closer to the pointt_{0} { = }\frac{\pi }{{{10}}}, the better the green curve is approximated to the raw blue curve(seen in the right graph of Fig.2)...
The notion of orthogonality is a generalization of perpendicularity. From elementary geometry, it is clear that two vectors in the plane are perpendicular if they meet at a right angle. This property of vectors can be generalized to vector spaces with an inner product (inner product spaces) in...
