Electrical Engineering Technologies Mathematics for Electrical Engineering Space vector vs. phasor To start with, we need to differentiate space vectors from the concept of phasors. While both of them can represent three phase voltages with three voltage vectors that are separated with 2π3, the magn...
It is hard to overstate the importance of the idea of a vector space, a concept that has found application in mathematics, engineering, physics, chemistry, biology, the social sciences, and other areas. What we encounter is an abstraction of the idea of vector space that we studied in ...
The topological vector space V (over a topological field K) is locally convex iff each element of some neighborhood base at O, is convex. A subset B of V is bounded iff for every neighborhood U of O and some positive t. When some open subset of V is bounded, V is locally bounded....
A vector embedding is, at its core, the ability to represent a piece of data as a mathematical equation.Google’s definition of a vector embeddingis“a way of representing data as points in n-dimensional space so that similar data points cluster together.” For people who have strong backgro...
Given a vector field \vec{F}(x, y, z) defined in the 3d space, the surface integral of the curl of \vec{F} in a closed surface S, equals the line integral of \vec{F} along the boundary curve C of this surface. \iint_S (\vec{\nabla} \times \vec{F}) d\vec{S} = \o...
Journal 2008, Applied Mathematics and ComputationMiroslav Morháč Chapter Vector spaces Important concepts Section 2.1 ► Addition, subtraction, and scalar multiplication of 2-tuples can be done graphically in the plane. Section 2.2 ► The zero vector in a vector space is unique. ► The ad...
The cross product of two vectors in three-dimensional space is given by: A×B=|ijkAxAyAzBxByBz| It results in a vector that is perpendicular to both A and B. Magnitude The magnitude of a vector A is given by: ||A||=Ax2+Ay2+Az2 It represents the length of the vector. Angle...

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. A line has a dimension of one (1D) because only one coordinate is needed to specify a point on it – for example...
Since y∈ V and since {xk} and {uk} are complete biorthonormal sets of nonzero vectors in an inner product space V, then y can be expressed as y=∑kckuk. Taking the inner product of both sides of this equation with xm yields 〈y,xm〉=〈∑kckuk,xm〉, or by linearity, 〈y...
