1.2. Polar Form
... Why this form? Because it satisfies several conditions and definitions.Complex numbers are often used to represent waves, and wavefunctions. The complex exponential works in the same way as polar form, multiplication and division are carried out simply by multiplying (for multiplication) or dividing ...

... as we move along a path between the points a and b, at each step we take the component of A which lies along the direction we are moving (given by the vector dl) and multiply it by the distance we move through. The line integral is the sum of all these individual values as we move from a to b. Conse ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
