根号2sin60°+根号2/2cos45°-根号3/2tan60°-根号3cos30°
问题描述：
根号2sin60°+根号2/2cos45°-根号3/2tan60°-根号3cos30°
答
根号2sin60°+根号2/2cos45°-根号3/2tan60°-根号3cos30°
=根号2×根号3/2+根号2×根号2/2-根号3/2×根号3/3-根号3×根号3/2
=根号6/2+1-1/2-3/2
=根号6/2-1
答
原式=√2*√3/2+√2/2*√2/2-√3/2*√3-√3*√3/2
=√6/2+1/2-3/2-3/2
=√6/2-1/2
答
根号2sin60°+根号2/2cos45°-根号3/2tan60°-根号3cos30°
=√2×√3/2+√2/(2×√2/2)-√3/2√3-√3×√3/2
=√6/2+1-1/2-3/2
=√6/2-1
