 P: 130 Hi guys... don't suppose anybody knows how to calculate the error function - erf(x) I know Matlab can calculate it - but is it possible to evaluate it without computational techniques (i.e. using computers)? $${erf}(x) = \frac{2}{\sqrt{\pi}}\int_0^x e^{-t^2} dt.$$ Would appreciate any feedback. thanks.
