sin(x)=0.014

解答

sin (x) = 0.014

x = 0.01400 \dots + 2 πn, x = π - 0.01400 \dots + 2 πn

度数

x = 0.80216 \dots^{\circ} + 36 0^{\circ} n, x = 179.19783 \dots^{\circ} + 36 0^{\circ} n

求解步骤

sin (x) = 0.014

使用反三角函数性质

sin (x) = 0.014

sin (x) = 0.014

的通解

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

x = arcsin (0.014) + 2 πn, x = π - arcsin (0.014) + 2 πn

x = arcsin (0.014) + 2 πn, x = π - arcsin (0.014) + 2 πn

以小数形式表示解

x = 0.01400 \dots + 2 πn, x = π - 0.01400 \dots + 2 πn

6 cos (2 x) + 8 sin (2 x) = 0

cos (x) = \frac{8}{17}, sin (x)

\frac{50}{sin ( 10 5 ^{\circ} )} = \frac{20}{sin ( x )}

csc (θ) = - 1.343

csc (θ) = - \frac{3}{2}, π < θ < \frac{3 π}{2}, sin (θ)
