Question

sin45°+cos30°/3-2cos60°-sin30°×(cos45°-sin60°)

Answer 1

sin45°+cos30°/3-2cos60°-sin30°×(cos45°-sin60°)
=(根2)/2+(根3)/6-1-1/2×((根2)/2-(根3)/2)
=(根2)/4+(5根3)/12-1

Answer 2

sin45°+cos30°/3-2cos60°-sin30°×(cos45°-sin60°)
=1/2√2+1/2√3/3-2×1/2-1/2×（1/2√2-1/2√3）
=1/2√2+1/6√3-1-1/4√2+1/4√3
=1/4√2+5/12√3-1
