    55See [http://ask.sagemath.org/question/549/evaluating-inverse-erf this ask.sagemath question] for background. 
     6
     7Defect because Sage can't make sense of a Maxima result:
     8{{{
     9sage: var('z,t')
     10(z, t)
     11sage: PDF = exp(-x^2 /2)/sqrt(2*pi)
     12sage: integralExpr = integrate(PDF,x,z,oo).subs(z==log(t))
     13sage: y = solve(integralExpr==z,t)[0].rhs().subs(z==1/4)   
     14sage: y
     15e^(sqrt(2)*inverse_erf(1/2))
     16sage: inverse_erf?
     17Object `inverse_erf` not found.
