sin(x -y)=s in(x) cos(y) -cos(x)sin(y) cos(x -y) = cos(x) cos(y)+sin(x)sin(y) tan(x) -tan(y) tan(x -y)= 1 + tan(x) tan(y) LAW OF SINES sin(A) sin(B) sin(C) = = a b c. DOUBLE-ANGLE IDENTITIES sin(2x)=2s in(x) cos(x) cos(2x) = cos 2 (x) -sin 2 (x) = 2 cos 2 (x) 1 =1-2sin 2-(x) 2 tan(x) tan(2x)= 1 -tan 2 (x) HALF-ANGLE IDENTITIES r ⇣ ⌘x 1 cos
