Question

find value of sin 15​

Answer 1

sin 15=1/√2 is the right ans

Answer 2

Question : Find value of Sin15°

Answer :

Sin15° = Sin(45°-30°)

Using formula, Sin(A+B) = SinA.CosB - CosA.SinB

We get ;

Sin45°.Cos30° - Cos45°.Sin30°

putting all values :

$\frac{1}{ \sqrt{2} } \times \frac{ \sqrt{3} }{2} \times \frac{1}{ \sqrt{2} } \times \frac{1}{2}$

and by solving,

$\frac{ \sqrt{3 - 1} }{2 \sqrt{2} }$

This is final answer!
