Question

find the value of sin 15​

Answer 1

Answer:

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

Step-by-step explanation:

sin15=sin (60-45)

Answer 2

Answer:

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 the answer!
