Title: Math Tutoring
Post by: tbonejc on December 05, 2011, 09:26:15 pm: Hey everyone. I'm starting to tutor on the side. If you know anyone that can use some help with their math let me know. I made a posting on Craigslist about it. You can check it out at http://phoenix.craigslist.org/evl/lss/2738270619.html (http://phoenix.craigslist.org/evl/lss/2738270619.html)
I have a Facebook page, http://www.facebook.com/pages/Math-Geek-Tutoring/234594729938875 (http://www.facebook.com/pages/Math-Geek-Tutoring/234594729938875) and can be followed on Twitter @MathTutoringAZ.
Please spread the word. I'm happy to help anyone I can.

Very tempting. If I get enough paying customers then sure!

There actually is no conventional method to integrate this. You can get an approximation by using the Taylor Series expansion, namely Σ(((x^2)^n)/n!). but there is no direct method to integrate this. How did you come up with this? Statistics and probablity uses e^(-x^2) which is the error function and can be manipulated to look like a normal density function that you can use tables to find an answer.
