Verified by Experts

The correct Answer is:

C

((2 tan 30^(@))/(1 -tan^(2)30^(@))) = ?
Text Solution
|
(1-tan^2 3 0^(@))/(1+tan^2 3 0^(@))=
Text Solution
|
(2 tan 30^(@))/(1 - tan^(2) 30^(@)) = tan ………………….
Text Solution
|
( 2 tan 30^(@))/(1+ tan^(2) 30^(@))=
Text Solution
|
(2 tan 30^(@))/(1 + tan^(2)30^(@)) =
Text Solution
|
(2 tan 30 ^@ ) /( 1 + tan ^ 2 30 ^@ )
Text Solution
|
(2 tan 30 ^@) /( 1 - tan ^ 2 30 ^@ )
Text Solution
|
(1-tan^2 30^@)/(1+tan^2 30^@) का मान है:
Text Solution
|
2 tan 30^(0) // 1+tan^(2) 30^(0)విలువ
