The expression cos(A-B) - cos(A+B) is equal to 1) -2sinAsinB 2) -2cosB 3) 2cosAcosB 4) 2sinAsinB So far, all I've gotten is cosxcosy + sinxsiny - cosxcosy - sinxsiny I don't know where to go from there.

Which of the following are identities? Check all that apply. a) tan x - tan y = sin(x-y)/cosxcosy b) 1 - tanxtany = sin(x+y)/sinxsiny c) tan(x-pie/4) = tanx-1 d) cos(x+pie/6) = -sin(x-pie/3)
