solvefor x,-f=sin(x)

解答

求解

x, - f = sin (x)

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

求解步骤

- f = sin (x)

交换两边

sin (x) = - f

使用反三角函数性质

sin (x) = - f

sin (x) = - f

的通解

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

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

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

\frac{1}{2} cos (2 x - \frac{π}{3}) + 4 = 0

sin (B) = \frac{16 sin ( 10 4 ^{\circ} )}{25}

sin (t) = \frac{3}{5}, cos (t) = \frac{4}{5}

cos (3 x) = 4 cos^{2} (x) - 3 cos (x)

2 sin (2 θ) = 0
