tan30°+2sin60°*cos0°+tan45°*sin90°+cos60°的解题过程和答案
tan30°+2sin60°*cos0°+tan45°*sin90°+cos60°的解题过程和答案
tan30°+2sin60°*cos0°+tan45°*sin90°+cos60°的解题过程和答案
tan30°+2sin60°*cos0°+tan45°*sin90°+cos60° = (√3/3) + 2√3/2 * 1 + 1 * 1 + (1/2) = 1/3 + √3 + 1 + 1/4 = 19/12 + √3
tan30°+sin60°-tan45°+cos0°＝?
tan30°+2sin60°*cos0°+tan45°*sin90°+cos60°的解题过程和答案
2cos60°+tan30°-sin60°
3tan30°+2sin60°-2tan45°
计算:sin60°+3-tan30°-(cos45°-2)^0
3tan30°-tan45°+2sin60°
2sin60°+4cos45°+3tan30°等于?
3tan30°-tan²45°-2sin60°
tan30°+sin60°+cos45°=?
tan30°sin60°-cot45°=?
3tan30°-tan45°+2sin60°=?3tan30°-tan45°+2sin60°=?
(tan30°+tan45°)/(1-tan30°tan45°)-2sin60°-sin^2 40°-cos^2 40°
tan45°-cos60°/sin60°×tan30°
cos60°/1+sin60°*1/tan30°的值
tan30°+sin60°/1-cos60°=
cos²45°+tan30°×sin60°=
cos²45°+tan30°·sin60°
cos²60°+tan30°×sin60°
