+2592 So in my Pre-Calc class, we just learned some identies of sin,cos, and tan.
Just wondering if anybody else, not CPhill or Alan, knows this stuff
\((Tan\alpha +Tan\beta)/(1-Tan\alpha*Tan\beta) = \)
\(Cos\alpha*Cos\beta -Sin\alpha*Sin\beta = ? \)
+129899 HAHAHA!!!!........what do you have against us???
First one ..... Tan (A + B)
Second one.........Cos (A + B)
+2592 I wrote that because i knew you two would know the anwser
