If a real function has a domain that is self-symmetric with respect to the origin, it may be uniquely decomposed as the sum of an even and an odd function, which are called respectively the even part (or the even component) and the odd part (or the odd component) of the function, and are defined by = + (), and = ().
It is possible for a function to be neither odd nor even, and for the case f(x) = 0, to be both odd and even. [20] The Taylor series of an even function contains only terms whose exponent is an even number, and the Taylor series of an odd function contains only terms whose exponent is an odd number. [21]
Parity (mathematics), indicates whether a number is even or odd Parity of a permutation, indicates whether a permutation has an even or odd number of inversions; Parity function, a Boolean function whose value is 1 if the input vector has an odd number of ones; Parity learning, a problem in machine learning; Parity of even and odd functions
The permutation is odd if and only if this factorization contains an odd number of even-length cycles. Another method for determining whether a given permutation is even or odd is to construct the corresponding permutation matrix and compute its determinant. The value of the determinant is the same as the parity of the permutation. Every ...
In Boolean algebra, a parity function is a Boolean function whose value is one if and only if the input vector has an odd number of ones. The parity function of two inputs is also known as the XOR function. The parity function is notable for its role in theoretical investigation of circuit complexity of Boolean functions.
The way into which particular variables and vectors sort out into either category depends on whether the number of dimensions of space is either an odd or even number. The categories of odd or even given below for the parity transformation is a different, but intimately related issue. The answers given below are correct for 3 spatial dimensions.

In mathematics, the term even is used in several senses related to odd: even and odd numbers, an integer is even if dividing by two yields an integer; even and odd functions, a function is even if f(−x) = f(x) for all x; even and odd permutations, a permutation of a finite set is even if it is composed of an even number of transpositions
