Sin 75 degrees in fraction.
Use some half angle formulas: #sin(theta/2) = +-sqrt((1-cos theta) / 2)# #cos(theta/2) = +-sqrt((1+cos theta) / 2)# Also use a known value #cos 30^o = sqrt(3)/2#. If we stick to the first quadrant, we can take the sign of the square root to be #+# in both cases.. #cos 15^o = sqrt((1+cos 30^o)/2)#
