function defined by integralperiodicitymean valueThe solutions of problems in differential equations, especially those which arise in physics and engineering, are frequently given in terms of integrals. Most often either the integrand of the integral representing the solution is unbounded or the domain ...
摘要: This paper studies the periodicity of the function defined as a definite integral with its upper limit being viewed as the variable.Two necessary and sufficient conditions are obtained,and a conclusion about the divergence of an improper integral with periodic integrand is drawn....
Both of these functions are defined by integrals. The gamma function is defined by the integral and the error function is defined by The integral in the definition of the error function cannot be evaluated using calculus, and instead must be computed numerically: math.gamma(5) # 24.0math.erf...
The historical account in each of the ten sections is followed by pedagogical comments. These refer to such issues as what a formula is, when and how to introduce functions, calculus without functions, functions defined on a "split domain", the desirability of the early introduction of power ...

There are other related functions that were not considered here, of most importance would be analogues of the exponential integrals Eiℰi and Enℰn , as well as the cosine integral CiCi . All of these functions are defined by an integral that is computed via the Cauchy principal value; ...

A function defined by f [ x_ ] : = expr is usually not needed to do calculations with expressions. Instead, one can give a name for the expression, such as f = expr, and use this name. The syntax of a function is needed to write more complex functions, such as recursive functions...
