Thus, the function g is applied after applying f to x. Reverse composition, sometimes denoted , applies the operation in the opposite order, applying first and second. Intuitively, reverse composition is a chaining process in which the output of function f feeds the input of function g.
The function g must equal the inverse of f on the image of f, but may take any values for elements of Y not in the image. A function f with nonempty domain is injective if and only if it has a left inverse. [21] An elementary proof runs as follows: If g is the left inverse of f, and f(x) = f(y), then g(f(x)) = g(f(y)) = x = y.
v. t. e. In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball". In certain formalisations of concatenation theory, also called string theory, string concatenation is a primitive notion.

Computation of a cyclic redundancy checkis derived from the mathematics of polynomial division, modulo two. In practice, it resembles long divisionof the binarymessage string, with a fixed number of zeroes appended, by the "generator polynomial" string except that exclusive oroperations replace subtractions.
They are commonly denoted by the symbols for the hyperbolic functions, prefixed with arc-or ar-. For a given value of a hyperbolic function, the inverse hyperbolic function provides the corresponding hyperbolic angle measure, for example arsinh(sinha)=a{\displaystyle \operatorname {arsinh} (\sinh a)=a}and sinh(arsinhx)=x ...
Pointwise. In mathematics, the qualifier pointwise is used to indicate that a certain property is defined by considering each value of some function An important class of pointwise concepts are the pointwise operations, that is, operations defined on functions by applying the operations to function values separately for each point in the domain ...
Post's inversion formula for Laplace transforms, named after Emil Post, [3] is a simple-looking but usually impractical formula for evaluating an inverse Laplace transform. The statement of the formula is as follows: Let f ( t ) {\displaystyle f(t)} be a continuous function on the interval [ 0 , ∞ ) {\displaystyle [0,\infty )} of exponential ...
