I'd be more sympathetic if people here didn't act like they knew what they were saying when they were saying something very much wrong.
Commenter Brendan Rizzo is an American (still living there) who really, really hates America. He used to make posts defending his country from anti-American attacks but got fed up with it all.

I bet that's why she's facepalming. His math is wrong!Now if it was her cosine.Actually sine of pi/2 is 1. pi/2 cosine is 0.Oh yeah. I haven't had to use trigonometry in a while, and I was too lazy to look it up. Now that you mention it, I remember.
