  2. Integral graph - Wikipedia

    en.wikipedia.org/wiki/Integral_graph

    In the mathematical field of graph theory, an integral graph is a graph whose adjacency matrix's spectrum consists entirely of integers. In other words, a graph is an integral graph if all of the roots of the characteristic polynomial of its adjacency matrix are integers. [1] The notion was introduced in 1974 by Frank Harary and Allen Schwenk. [2]

  3. Cayley graph - Wikipedia

    en.wikipedia.org/wiki/Cayley_graph

    In mathematics, a Cayley graph, also known as a Cayley color graph, Cayley diagram, group diagram, or color group, [1] is a graph that encodes the abstract structure of a group. Its definition is suggested by Cayley's theorem (named after Arthur Cayley ), and uses a specified set of generators for the group.

    en.wikipedia.org/wiki/Lists_of_integrals

    Integration is the basic operation in integral calculus.While differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions, integration does not, so tables of known integrals are often useful.

  5. Integral curve - Wikipedia

    en.wikipedia.org/wiki/Integral_curve

    An integral curve for X passing through p at time t 0 is a curve α : J → M of class C r−1, defined on an open interval J of the real line R containing t 0, such that α ( t 0 ) = p ; {\displaystyle \alpha (t_{0})=p;\,}

  6. Gaussian function - Wikipedia

    The integral / for some real constants a, b and c > 0 can be calculated by putting it into the form of a Gaussian integral.First, the constant a can simply be factored out of the integral.

    For help on the process, see Wikipedia:How to draw a diagram with Inkscape. This tutorial aims to instruct a beginner on the basic principles of vector graphics using Microsoft Word (Office 97 or later). The basic principles are the same in other drawing programs such as CorelDraw or the free and open source OpenOffice.org.

  8. Log–log plot - Wikipedia

    en.wikipedia.org/wiki/Log–log_plot

    In science and engineering, a log–log graph or log–log plot is a two-dimensional graph of numerical data that uses logarithmic scales on both the horizontal and vertical axes. Power functions – relationships of the form y = a x k {\displaystyle y=ax^{k}} – appear as straight lines in a log–log graph, with the exponent corresponding to ...

    The Lebesgue integral extends the integral to a larger class of functions. It also extends the domains on which these functions can be defined. L'Hôpital's rule L'Hôpital's rule or L'Hospital's rule uses derivatives to help evaluate limits involving indeterminate forms. Application (or repeated application) of the rule often converts an ...
