How does Trigonometry & Calculus apply to sound/acoustics etc.?

LOL. I feel you, But I think it has something to do with decibels, frequencies and area. Aye, I go by trial and error. But the important thing for you to remember is to never give up. I know it sounds lame, but it would be lamer if you got that far only to give up on a piece of paper that may change your life forever, a href="http://www.youtube.com/watch?v=Eb_-gKCPa7U" rel="nofollow"http://www.youtube.com/watch?v=Eb_-gKCPa…/a keep hustlin'!
