what exactly does [tex]\cos \theta_1 \cos \theta_2[/tex] represent, in relation to the angles? is this a dot product? i have played, and don't really see what this product is supposed to represent.(adsbygoogle = window.adsbygoogle || []).push({});

EDIT: you know, i may have just answered my own question with a mere trig identity... perhaps i will figure this thing out i'm working on pretty soon.....
