An inexact differential is a differential for which the integral over some two paths with the same end points is different. Specifically, there exist integrable paths ,: [,] such that () = (), () = and In this case, we denote the integrals as | and | respectively to make explicit the path dependence of the change of the quantity we are considering as .
A second fact that the theory must prove is that given any Gödel number G(F(x)) of a formula F(x) with one free variable x and any number m, there is a Gödel number of the formula F(m) obtained by replacing all occurrences of G(x) in G(F(x)) with G(m), and that this second Gödel number can be effectively obtained from the Gödel number G(F(x ...
Change of variables is an operation that is related to substitution. However these are different operations, as can be seen when considering differentiation or integration (integration by substitution). A very simple example of a useful variable change can be seen in the problem of finding the roots of the sixth-degree polynomial:
In simple terms, a method can be devised so that every formula or statement that can be formulated in the system gets a unique number, called its Gödel number, in such a way that it is possible to mechanically convert back and forth between formulas and Gödel numbers. The numbers involved might be very long indeed (in terms of number of ...
The Bernoulli model admits a complete statistic. [1] Let X be a random sample of size n such that each X i has the same Bernoulli distribution with parameter p. Let T be the number of 1s observed in the sample, i.e. = =. T is a statistic of X which has a binomial distribution with parameters (n,p).

The main idea is to express an integral involving an integer parameter (e.g. power) of a function, represented by I n, in terms of an integral that involves a lower value of the parameter (lower power) of that function, for example I n-1 or I n-2. This makes the reduction formula a type of recurrence relation. In other words, the reduction ...
The incomplete elliptic integral of the first kind F is defined as (,) = = (;) = .This is Legendre's trigonometric form of the elliptic integral; substituting t = sin θ and x = sin φ, one obtains Jacobi's algebraic form:
