It cannot be done using a finite number of elementary functions (this can be proved, by the way). An answer can be found using the Error Function erf(x): Error function - Wikipedia, the free encyclopedia

yup.. this is a very interesting question.. it cannot be solved directly due the the reason provided above.. however, the ans can be approximate by converting e^(x^2) to some polynomial using lagrange interpolation or using taylor series. It should be able to get some very close approximation

wow thanks very much guys! wondered why i was struggeling so much!

Thanks
