hope it helps..
have a great day!!
has no antiderivative in terms of elementary functions (polynomials, exponentials, logarithms, trigonometric functions, etc), but there is a special function defined to fit that role called the error function, 
, where
By the fundamental theorem of calculus, we can see that
which means we have
4*0.23
0.92
