sin2A = 2tanA/1+tan²
given :- tanA = 1/√3
so
sin2A = 2×1√3/1+ (1/√3)²
= 2/√3 ×3/4
= √3/2

Given : The value of tanA is 1/√3
To find : The value of sin2A
Solution :
We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the value of sin2A)
Here, we will be using general trigonometric identities, in order to calculate the value of sin2A.
So,
= sin2A
=
(This value of sin2A will be considered as the final result of this mathematical problem.)
Used formula :
- sin2A =
Hence, the value of sin2A is
