    Wow, IE sucks at math!  ;-)

    How much better it would be to have MathML formulas instead of PNG images!

  2. Actually I wrote this using a 64-bit version of Firefox:

    Mozilla/5.0 (Windows; U; Windows NT 6.0 x64; en-US; rv:1.9a8pre) Gecko/2007090213 Minefield/3.0a8pre

    http://www.mozilla-x86-64.com/

    This doesn’t seem to be MathML-enabled.

    Agreed, MathML will be really cool when browsers start to support it.

    It has been a while since my last calculus homework, but this all came rushing back.  Thanks, I guess!  A little mental workout is always a good thing.

    a=0 is the only solution for the last equation.

    Of course, the whole point of the original comment about pi plus C (which ignores all the other errors) was to bring in irony that even the commenter "sucks at math".

    First off the integral of x^2 is not even close to pi, hence why the person writing on the blackboard sucks at math. It is really http://www.wolframalpha.com/input/?i=integral+of+x^2 . Where as the + C is there to add insult to injury. Besides that, you cant add limits of integration to an indefinite integral for fun.
