Level of Im(ƒ)=0 is shown with a thick green line. Inverse Error Function Excel Wolfram Demonstrations Project» Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more. Because of this, if you are simply interested in plotting $y(t)$, then one way to do it is to avoid the inverse-map altogether, forward-map the $x$-axis, and then take that into http://mathworld.wolfram.com/InverseErfc.html The error and complementary error functions occur, for example, in solutions of the heat equation when boundary conditions are given by the Heaviside step function.

Sloane, N.J.A. The Taylor series about 1 is given by (8) (OEIS A002067 and A007019). A Mathematica fix would be best, obviously, but I'm not sure how to do that. Given random variable X ∼ Norm [ μ , σ ] {\displaystyle X\sim \operatorname {Norm} [\mu ,\sigma ]} and constant L < μ {\displaystyle L<\mu } : Pr [ X

The error function is related to the cumulative distribution Φ {\displaystyle \Phi } , the integral of the standard normal distribution, by[2] Φ ( x ) = 1 2 + 1 These generalised functions can equivalently be expressed for x>0 using the Gamma function and incomplete Gamma function: E n ( x ) = 1 π Γ ( n ) ( Γ While the mark is used herein with the limited permission of Wolfram Research, Stack Exchange and this site disclaim all affiliation therewith. This usage is similar to the Q-function, which in fact can be written in terms of the error function.
