Integral

Okay..so I tried to do the integral. It comes out as 2009/2 times the error function of a constant times x. The constant is approx .036. So we have (2009/2)erf(.036x). I assume it should be read as 2009/2 and not 1004.5 just because of the year we are in.

Is that funny? Help! Do I need to expand the erf? I have no intention of trying that.
