Question 231967: Use the sum or difference identities to find the exact value of sin 105 degrees. Answer by Alan3354(69443) ( Show Source ): You can put this solution on YOUR website!

sin 105 degrees. ** sin(x/2)=±√((1-cosx)/2) sin 105º=sin (210º/2)=±√((1-cos210º)/2) cos 210º=cos 30º=-√3/2 (in quadrant III where cos0) =±√((1+√3/2)/2) multiply by LCD 2 =±√((2+√3)/4) take sqrt of positive root because sin 105º in quadrant II is positive sin 105º=√(2+√3)/2
