solvefor y,x=arcsin(y)

解答

求解

y, x = arcsin (y)

y = sin (x)

求解步骤

x = arcsin (y)

交换两边

arcsin (y) = x

使用反三角函数性质

arcsin (y) = x

arcsin (x) = a \Rightarrow x = sin (a)

y = sin (x)

y = sin (x)

2 sin^{2} (x) + 5 sin (x) = 3

∣ sin (x) ∣ = \frac{1}{2}

sec^{2} (θ) = 2 tan (θ)

2 sin (2 x) + 2 = 0

2 cos^{2} (θ) - 3 sin (θ) + 2 = 0
