Question

if tan A =√3, then what is tan 2A​

Answer 1

Answer:

As here 

tanA=√3

A=60

now

tan2(60)

tan120

tan(180-60)

According to class 11 property

tan(-60)        

-tan(60)

=-√3

But in 10th class the value of Ф cannot be exced from 90 so whenever we get a number more than 90 we have to divide by 2 and write down the value

Answer 2

Answer:

tan2A=-√3

Step-by-step explanation:

tanA =√3

{since tan60°=√3}

tanA=tan60°

A=60°

tan2A=tan(2*60)°

{since tan2x=2tanx/1-tan²x}

tan2A=2tan60°/1-tan²60°

tan2A=2×√3/1-(√3)²

tan2A=2√3/1-3

tan2A=2√3/-2

tan2A=-√3
