sin sq 5°+sin sq6°+.......+sin sq 45°+......+sin(90°-5°)+
sin(90°-6°)=sin sq 5°+sin sq 6°+.......+ 1\root2+......+cos5°+cos6°=(sin sq5°+cos sq5°)+......+1/root2+......+(sin6°+cos6°)=40/root2
sin(90°-6°)=sin sq 5°+sin sq 6°+.......+ 1\root2+......+cos5°+cos6°=(sin sq5°+cos sq5°)+......+1/root2+......+(sin6°+cos6°)=40/root2
