Half-Angle formulas sin s/2=+-sqrt((1-cos s)/2), (note:+ or - answer depends on value of sin s/2 not sin s.) cos s/2=+-sqrt((1+cos s)/2), (note:+ or - answer depends on value of cos s/2 not cos s.) tan s/2=sin s/(1+cos s) sin 67.5=sin 135/2=sqrt((1-cos 135)/2) =sqrt((1+√2/2)/2)=sqrt((2+√2)/4) =sqrt(2+√2)/2 Hope it helps....
