sin(x)=0.26

解答

sin (x) = 0.26

x = 0.26302 \dots + 2 πn, x = π - 0.26302 \dots + 2 πn

度数

x = 15.07006 \dots^{\circ} + 36 0^{\circ} n, x = 164.92993 \dots^{\circ} + 36 0^{\circ} n

求解步骤

sin (x) = 0.26

使用反三角函数性质

sin (x) = 0.26

sin (x) = 0.26

的通解

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

x = arcsin (0.26) + 2 πn, x = π - arcsin (0.26) + 2 πn

x = arcsin (0.26) + 2 πn, x = π - arcsin (0.26) + 2 πn

以小数形式表示解

x = 0.26302 \dots + 2 πn, x = π - 0.26302 \dots + 2 πn

\frac{2 - 2 sin ( x )}{a} = \frac{2}{sin ( x )}

sin (B) = \frac{1}{3}

cos (7 x) = sin (5 x - 6)

100 = 211.49 - 20.96 cosh (0.03291765 x)

3 sec^{2} (x) + 4 cos^{2} (x) = 7
