    3.3.3 The Standard" Form of the Solution γ > 1. 4 Solution around x = 1. 5 Analysis of the solution in terms of the difference γ − α − β of the two roots.

  3. Vector fields in cylindrical and spherical coordinates

    en.wikipedia.org/wiki/Vector_fields_in...

    Note: This page uses common physics notation for spherical coordinates, in which is the angle between the z axis and the radius vector connecting the origin to the point in question, while is the angle between the projection of the radius vector onto the x-y plane and the x axis. Several other definitions are in use, and so care must be taken ...

  4. Parametric equation - Wikipedia

    en.wikipedia.org/wiki/Parametric_equation

    The standard method for computing a parametric form of the solution is to use Gaussian elimination for computing a reduced row echelon form of the augmented matrix. Then the unknowns that can be used as parameters are the ones that correspond to columns not containing any leading entry (that is the left most non zero entry in a row or the ...

  5. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators, it is usually known as "SCI" display mode.

  6. Differential form - Wikipedia

    en.wikipedia.org/wiki/Differential_form

    is a smooth section of the projection map; we say that ω is a smooth differential m-form on M along f −1 (y). Then there is a smooth differential (m − n)-form σ on f −1 (y) such that, at each x ∈ f −1 (y), = /. This form is denoted ω / η y.

  7. Covariance and correlation - Wikipedia

    en.wikipedia.org/wiki/Covariance_and_correlation

    [1] [2] Both describe the degree to which two random variables or sets of random variables tend to deviate from their expected values in similar ways. If X and Y are two random variables, with means (expected values) μ X and μ Y and standard deviations σ X and σ Y, respectively, then their covariance and correlation are as follows: covariance

  8. Canonical form - Wikipedia

    en.wikipedia.org/wiki/Canonical_form

    Each one is converted into a canonical form by sorting. Since both sorted strings literally agree, the original strings were anagrams of each other. In mathematics and computer science, a canonical, normal, or standard form of a mathematical object is a standard way of presenting that object as a mathematical expression. Often, it is one which ...

    The electric charge Q, third component of weak isospin T 3 (also called T z, I 3 or I z) and weak hypercharge Y W are related by = +, (or by the alternative convention Q = T 3 + Y W). The first convention, used in this article, is equivalent to the earlier Gell-Mann–Nishijima formula. It makes the hypercharge be twice the average charge of a ...
