Question

Find
Sin 2 (30degrees)
​

Answer 1

Sin 2 (30)°=
`(√(3) )/(2)`

Explanation:

Explanation:-

Given that Sin 2 (30)°

we know that the formula sin2θ = 2sinθ cosθ

Given that θ = 30°

Now

sin2(30)° = 2sin30° cos30°

`= 2 ( (1)/(2) X (√(3) )/(2) )`

After cancellation, we get

Sin 2 (30)° =
`(√(3) )/(2)`

Final answer:-

Sin 2 (30)° =
`(√(3) )/(2)`
