sin60°+cos60°·tan45°+1/2根号1-2tan30°+tann^230du5=?
sin60°+cos60°·tan45°+1/2根号1-2tan30°+tann^230du5=?
sin60°+cos60°·tan45°+1/2根号1-2tan30°+tann^230du5=?
sin60°+ cos60°·tan45°+1/2√(1-2tan30°) +tan²30°
= √3/2 + 1/2 * 1 +1/2 *√(1-2√3/3) + (√3/3)²
= √3/2 + 1/2 +1/2 *√[√3-1)²/3] + 1/3
= √3/2 + 1/2 +1/2 - √3/6 + 1/3
= (4 + √3)/3
1.tan45°-sin30° =1-0.5=0.5 2.cos60°+sin45°-tan30° =0.(3)根号2 /2 sin45°+sin60°-2cos45°。 =(√2/2)×(√2/2)+
不知道
sin60°+ cos60°·tan45°+1/2√(1-2tan30°) +tan²30°
= √3/2 + 1/2 * 1 +1/2 *√(1-2√3/3) + (√3/3)²
= √3/2 + 1/2 +1/2 - √3/6 + 1/3
= (4 + √3)/3
tan45°-cos60°/sin60°×tan30°
tan45°-cos60°/sin60°减tan60°
计算:sin60°cos60°—tan45°
tan45°-cos60°/sin60°×tan30° tan45°-cos60°/先除以sin60°之后,得到的数在与tan30° 相乘
