0=sin(x^2)

解答

0 = sin (x^{2})

解答

x = 2 πn, x = - 2 πn, x = π + 2 πn, x = - π + 2 πn

+1

度数

x = 0^{\circ} + 143.61922 \dots^{\circ} n, x = 0^{\circ} - 143.61922 \dots^{\circ} n, x = 0^{\circ} + 175.89690 \dots^{\circ} n, x = 0^{\circ} - 175.89690 \dots^{\circ} n

求解步骤

0 = sin (x^{2})

交换两边

sin (x^{2}) = 0

sin (x^{2}) = 0

的通解

sin (x)

x^{2} = 0 + 2 πn, x^{2} = π + 2 πn

x^{2} = 0 + 2 πn, x^{2} = π + 2 πn

解

x^{2} = 0 + 2 πn : x = 2 πn, x = - 2 πn

x^{2} = 0 + 2 πn

0 + 2 πn = 2 πn

x^{2} = 2 πn

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = 2 πn, x = - 2 πn

化简

2 πn : 2 πn

2 πn

使用根式运算法则:

n ab = n a n b,

假定

a \geq 0, b \geq 0

= 2 πn

化简

- 2 πn : - 2 πn

- 2 πn

使用根式运算法则:

n ab = n a n b,

假定

a \geq 0, b \geq 0

= - 2 πn

x = 2 πn, x = - 2 πn

解

x^{2} = π + 2 πn : x = π + 2 πn, x = - π + 2 πn

x^{2} = π + 2 πn

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = π + 2 πn, x = - π + 2 πn

x = 2 πn, x = - 2 πn, x = π + 2 πn, x = - π + 2 πn

3 cos (2 θ) = 0

4cos(2x)+2sin(x)=1,0<= x<= 360

4 cos (2 x) + 2 sin (x) = 1, 0^{\circ} \leq x \leq 36 0^{\circ}

3 csc (θ) + 5 = 0

cos(x/3)-cos(x/(15))=0

cos (\frac{x}{3}) - cos (\frac{x}{15}) = 0
