The Gaussian integral, also known as the Euler–Poisson integral, is the integral of the Gaussian function $${\displaystyle f(x)=e^{-x^{2}}}$$ over the entire real line. Named after the German mathematician Carl Friedrich Gauss, the integral is $${\displaystyle \int _{-\infty }^{\infty }e^{-x^{2}}\,dx={\sqrt {\pi }}.}$$ 展开
