Question

यदि cos A=√3/2 हो, तो tan 2A का मान ज्ञात kro answer please friends ​

Answer 1

Answer:

-√3

Step-by-step explanation:

cos A = √3/2 = cos 60°

tan 2A = tan (60°×2) = tan 120° = tan (180-60)° = -tan 60° = -√3

Answer 2

Given:- cos A = √3/2

so, we can say A = 30°

so, tan 2A = tan 2• 30°

= tan 60°

= √3.

Hence, tan 2A = √3.
