(cot60°-sin60°)÷(cos45°+1/2 tan45°-cot30°)大神们帮帮忙
(cot60°-sin60°)÷(cos45°+1/2 tan45°-cot30°)大神们帮帮忙
(cot60°-sin60°)÷(cos45°+1/2 tan45°-cot30°)大神们帮帮忙
原式=(根号3/3-根号3/2)/(1/2+1/2-根号3) =(-根号3/6) /(1-根号3) =(3+根号3)/12
sin60°*cot60°-tan45°
(cot60°-sin60°)÷(cos45°+1/2 tan45°-cot30°)大神们帮帮忙
cot60°-2cos60°-2sin60°
计算题sin60°+cos30°+tan30°*cot60°详细步骤
1)cos60°/sin60°-sin45°2)(1-tan60°)的绝对值+2sin²45°3)(cot60°-sin60°)/sin²45°×tan30°4)[根号(tan30°-cos30°)² ]+(cos60°-cot60°)的绝对值
化简 sin²30°+cos²30°+tan45°/cot60°
计算tan30°cot60°+cos的平方30°-sin的平方45°tan45°、、、快
sin60°-1除以sin60°+1(sin60°-1)除以(sin60°+1)多少?
cos²45°+sin60°*tan30°-√ (1-tan60°)²
cos²45°+tan30°×sin60°=
cos²45°+tan30°·sin60°
cos²60°+tan30°×sin60°
为什么sin60°+x =cos 30°-x?
根号12 + cos-30°- 4sin60°=?
谁能帮我我计算(sin60-cos30)/(tan22·tan68)-cot60!
2sin60°-cos²-30°+tan 60°cos² 45°
cos方30°cos²30°是多少?4sin60° 是多少?
(cos60°)+(sin60°)是多少
