... The expression r(cos θ + i sin θ) is called the trigonometric form (or polar form) of the complex number x + yi. The expression cos θ + i sin θ is sometimes abbreviated cis θ. Using this notation, r(cos θ + i sin θ) is written r cis θ. The number r is the absolute value (or modulus) of x + yi, and θ ...

... defined on R. Is C 1 (R) a subspace of F ? Why or why not? (a) The zero function, f (t) = 0 for all t ∈ R, is in C 1 (R), since f (t) is continuous and f 0 (t) = 0, which is also continuous. Let g, h ∈ C 1 (R), and let c be a scalar. (b) We have that (g + h)(t) = g(t) + h(t) is continous on R, and ( ...

... The 3 terms on the left hand side are mutually orthogonal flux components. To model an anisotropic system such as a magnetized plasma we set the x3 term tangential to the field lines. This is the parallel term. The x1 and x2 terms are the perpendicular, or radial, terms. The conduction coefficients, ...

Cartesian tensor
In geometry and linear algebra, a Cartesian tensor uses an orthonormal basis to represent a tensor in a Euclidean space in the form of components. Converting a tensor's components from one such basis to another is through an orthogonal transformation.The most familiar coordinate systems are the two-dimensional and three-dimensional Cartesian coordinate systems. Cartesian tensors may be used with any Euclidean space, or more technically, any finite-dimensional vector space over the field of real numbers that has an inner product.Use of Cartesian tensors occurs in physics and engineering, such as with the Cauchy stress tensor and the moment of inertia tensor in rigid body dynamics. Sometimes general curvilinear coordinates are convenient, as in high-deformation continuum mechanics, or even necessary, as in general relativity. While orthonormal bases may be found for some such coordinate systems (e.g. tangent to spherical coordinates), Cartesian tensors may provide considerable simplification for applications in which rotations of rectilinear coordinate axes suffice. The transformation is a passive transformation, since the coordinates are changed and not the physical system.
