Compound Angle Formula for Trigonometry

COMPOUND ANGLE FORMULA

Sin(A+B)= SinA CosB+CosA SinB
Sin(A-B)= SinA CosB-CosA SinB
Cos(A+B)= CosA  CosB-SinA SInB
Cos(A-B)= CosA CosB+Sin ASInB
Tan(A-B)= (TanA+TanB)/(1-TanATanB)
Tan(A+B)= (TanA-TanB)/(1+TanATanB)
Cot(A+B)= (CotACotB-1)/(CotB+CotA)
Cot(A-B)= (CotACotB+1)/(CotB-CotA)
