sin30°·tan45°+根号2·cos45°+sin60°·tan60°
sin30°·tan45°+根号2·cos45°+sin60°·tan60°

sin30°·tan45°+根号2·cos45°+sin60°·tan60°
sin30°·tan45°+根号2·cos45°+sin60°·tan60°
=1/2x1+√3x√2/2+√3/2x√3
=1/2+√6/2+3/2
=2+√6/2

2

原式=1/2*1+根号2*(根号2)/2+(根号3)/2*根号3
=1/2+1+3/2
=3

=1/2×1+根号2×根号2/2+根号3×根号3/2
=1/2+1+3/2
=3


1/2*1+根号2*根号2+根号3/2*根号3

=1/2+2+3/2
=4

sin30°=1/2
tan45°=1
cos45°=二分之根号2
sin60°=二分之根号3
tan60°=根号3
所以原式=1/2×1+根号2×二分之根号2+二分之根号3×根号3
=3
以上即为我的解答过程,希望对你有所帮助!
