ERFC(x)
- Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle x} is the lower limit.
Description
- This function gives the complementary ERF function.
- The complementary error function is the error function with the limit x and infinity. It is denoted by erfc(x).
- It is also called scaled complementary error function.
- ERFC is defined by:
Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle ERFC(x)=\frac{2}{\sqrt{\pi}}\int\limits_{x}^{\infty}e^{-t^2} dt=1-ERF(x)} .
- This function will return the result as error when x is nonnumeric or negative.
Examples
- ERFC(3)=0.0000219610
- ERFC(2)=0.00467776242
- ERFC(0)=1
- ERFC(-2)=NAN
