(), where (2n − 1)!! is the double factorial of (2n − 1), which is the product of all odd numbers up to (2n − 1). This series diverges for every finite x , and its meaning as asymptotic expansion is that for any integer N ≥ 1 one has erfc x = e − x 2 x π ∑ n = 0 N − 1 ( − 1 ) n ( 2 n − 1 ) ! !
A charbroiler (also referred to as a chargrill, char-broiler or simply broiler) is a commonly used cooking device consisting of a series of grates or ribs that can be heated using a variety of means, and is used in both residential and commercial applications for an assortment of cooking operations.

Physically, time invariance means system’s response does not depend on what time the input begins. For example, if a spring-mass system is at equilibrium, it will respond to a given force in the same way, no matter when the force was applied. When the time-invariant system is also linear, it is called a linear time-invariant system (LTI system).

Octave provides both erf and erfc for real and complex arguments. PARI/GP: provides erfc for real and complex arguments, via tanh-sinh quadrature plus special cases. Perl: erf (for real arguments, using Cody's algorithm [5]) is implemented in the Perl module Math::SpecFun; Python: Included since version 2.7 as math.erf() and math.erfc() for
