Answer 2

Step-by-step explanation:

sorry for all

but i can mention max

1) sin²A+cos²A=1

2) sec²A-tan²A=1

sin2A=2SinA.cosA

sin2A=2tanA/(1+tan²A)

Cos2A=2cos²A-1

Cos2A=1-2sin²A

Cos2A=cos²A-sin²A

cos2A={1-tan²A}/{1+tan²A}

tan2A=2tanA/(1-tan²A)

tan(A+B) ={ tanA +tanB}/{1-tanA.tanB}

tan(A-B) ={tanA-tanB}/{1+tanA.tanB}}
