The direct sum is a special way of combining several objects into one general object.¬(¬A) ⇔ A x ≠ y ⇔ ¬(x = y)∧(The bun symbol ⊕, or the coproduct symbol ∐, is used; ⊻ is only for logic.)Most commonly, for vector spaces U, V, and W, the following consequence is used: is not an element of everywhere, set theory a ∈ S means a is an element of the set S; [6] a ∉ S means a is

The way I explain it to myself is by saying Mathematica has two (types of) heads ;-) One type is for expressions such as f[x] and the other is for expressions such as 5. I even have names for them: explicit and implicit heads. Then I conclude: Apply replaces explicit heads only. Now, in {1,2}, the head is an explicit one.

The most basic symbols are the decimal … For example, depending on context, the triple bar "≡" may represent congruence or a definition. However, in mathematical logic, numerical equality is sometimes represented by "≡" instead of "=", with the latter representing equality of well-formed formulas. In short, convention dictates the meaning. A commonly encountered constant defined as \hbar\equiv {h\over 2\pi}=1.0546\times 10^{-27} {\rm\ erg\ s}=1.0546\times 10^{-34}{\rm\ J\ s}, where h is Planck's constant. h-bar commonly occurs in applications involving angular momentum.

Mathematica Overview The Mathematica function NDSolve is a general numerical differential equation solver. It can handle a wide range of ordinary differential equations (ODEs) as well as some partial differential equations (PDEs). In a system of ordinary differential equations there can be any number of

The Mathematica Trajectory It's Come a Long Way in Three Decades. The 500+ functions from Mathematica 1 are still in Mathematica 12—but there are now nearly 6,000, as well as a huge range of important new ideas that dramatically extend the vision and scope of the system.

OverHat[expr] displays with a hat over expr.

This is a re-phrasing of a TeX question that has a solution in TeX: https://tex.stackexchange.com/questions/309349/crossing-a-symbol-like-p-similar-to-one-like-hbar?noredirect=1&lq=1 Sqrt [ a b] is not automatically converted to Sqrt [ a] Sqrt [ b]. These conversions can be done using PowerExpand, but will typically be correct only for positive real arguments. For certain special arguments, Sqrt automatically evaluates to exact values. Sqrt can be evaluated to arbitrary numerical precision. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

In short, convention dictates the meaning. A commonly encountered constant defined as \hbar\equiv {h\over 2\pi}=1.0546\times 10^{-27} {\rm\ erg\ s}=1.0546\times 10^{-34}{\rm\ J\ s}, where h is Planck's constant. h-bar commonly occurs in applications involving angular momentum. It is implemented in Mathematica as PlanckConstantReduced in the Mathematica add-on package Miscellaneous`PhysicalConstants` (which can be loaded with the “$” symbol in mathematica output. Ask Question Asked 8 years, 10 months ago. This is why I made my LagrangePoly function accept the symbol that the polynomial is meant to be in. I used LagrangePoly[list_, var_:x], which defaults to the global symbol x.

Wolfram Science. Technology-enabling science of the computational universe. Wolfram Natural Language Understanding System. Knowledge-based, broadly deployed natural language. The symbol h is used to express the value of the Planck constant in J⋅s/cycle, and the symbol ħ ("h-bar") is used to express its value in J⋅s/radian.

Ask Question Asked 8 years, 10 months ago. This is why I made my LagrangePoly function accept the symbol that the polynomial is meant to be in. I used LagrangePoly[list_, var_:x], which defaults to the global symbol x. The symbol "=" together with "Df" is used to indicate "is defined as", whereas in sections 13 and following, "=" is defined as (mathematically) "identical with", i.e., contemporary mathematical "equality" (cf.

Though the solutions are numbers themselves these are symbolic calculations, I didn't use more elaborate equations to simplfy things. Line style, marker, and color, specified as a character vector or string containing symbols. The symbols can appear in any order. You do not need to specify all three characteristics (line style, marker, and color). For example, if you omit the line style and specify the marker, then the plot shows only the marker and no line. The symbol for greater than or equal to <= and the opposite is referred to as an "inequality".

SymPy is a Python library for symbolic mathematics. It aims to be an alternative to systems such as Mathematica or Maple while keeping the code as simple as possible and easily extensible. SymPy is written entirely in Python and does not require any external libraries.

This calculation consists of taking partial derivatives of the metric tensor components and one tensor operation. In Mathematica, the dot product, typically used for vectors and matrices, is also able to take tensors and contract indices.
