2023年8月27日 · sin80°=0.9848。 用三角函数公式：sin80度=sin (80度)=对边长度÷斜边长度=sin (80度)=sin (80π/180)，其中，80π/180是80度转换成弧度的结果。 因为数学计算中通常使用弧度而不是角度，所以需要将角度转换为弧度。 最后，可以使用计算器或其他数学工具来得出sin80度的具体值。 在大多数计算器中，直接输入sin (80)即可得到sin80度的结果，约为0.9848。 sin80度等于多少sin80°=0.9848。 用三角函数公式：sin80度=sin (80度)=对边长度÷斜边长度=sin (80 …

Use our sin (x) calculator to find the sine of 80 degrees - sin (80 °) - or the sine of any angle in degrees and in radians.

Sin 80 degrees is the value of sine trigonometric function for an angle equal to 80 degrees. Understand methods to find the value of sin 80 degrees with examples and FAQs.

正弦函数具有周期性，它的周期为2π(即360度)。这意味着sin(θ + 2π) = sinθ，也就是说，正弦函数每隔2π的角度重复一次。 在直角三角形中，如果已知一个角度θ和斜边的长度，可以通过sinθ = 对边 / 斜边来计算对边的长度。

2015年8月17日 · sin80度怎么求用什么公式？根据三倍角公式，sin(3a) = 3sin(a)-4(sin(a))^3，可得sin(240°) = 3sin(80°)-4(sin(80°))^3。设sin(80°)=x，则上式变为sin(240°) =3x-4x^3。易知sin(240°) =-√3/2，则有3x-4x^
