Question 615248: Use difference of two angles identity to find the exact value of sin 15 degrees.
*I used Sin(A - B)= Sin A cos B - cos A sin B, but came to radical 2 x radical 3 divided by 4 - radical 2 divided by 4....I dont not know how to simplifiy it further.

Use difference of two angles identity to find the exact value of sin 15 degrees.
sin 15�=sin(45-30)
=(sin45cos30-cos45sin30)
=√2/2*√3/2-√2/2*1/2
=√6/4-√2/4
=(√6-√2)/4
