Oh thanx a lot! I hope It's better if u correct that. It's misleading.

Hey, I just joined this site. It looks like "math is fun" is really fun and very useful. I am just new to my AL's. I've got many questions and hope you'll help me to find answers.
"Cos(A-B) - Cos(A-B) = 2SinASinB"
I saw this equation on this site. But it is quite different from what i learned in the class. What i lerned was this. "Cos(A-B) - Cos(A+B) = 2SinASinB" which one is correct?
