Question

FindSin 2 (30degrees)​

Answer 1

Answer:

Sin 2 (30)°=  $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

Explanation:-

Given that   Sin 2 (30)°

we know that the formula  sin2θ = 2sinθ cosθ

   Given that θ = 30°

   Now  

         sin2(30)° = 2sin30° cos30°

                                             $= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )$

       After cancellation, we get

                           Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Final answer:-

          Sin 2 (30)° = $\frac{\sqrt{3} }{2}$
