Question

write all compound angles formulas
le, sin (A+B), sin (A-B) ...etc​

Answer 1

Answer:

The compound angles formulae are:-

Step-by-step explanation:

1)sin(A+B)=sinAcosB+cosAsinB

2)sin(A-B)=sinAcosB-cosAsinB

3)cos(A+B)=cosAcosB-sinAsinB

4)cos(A-B)=cosAcosB+sinAsinB

5)tan(A+B)=(tanA+tanB)/(1-tanAtanB)

6)tan(A-B)=(tanA-tanB)/(1+tanAtanB)
