x^{2} = \frac{π}{2} + 2 πn

x^{2} = \frac{π}{2} + 2 πn

解

x^{2} = \frac{π}{2} + 2 πn : x = \frac{π + 4 πn}{2}, x = - \frac{π + 4 πn}{2}

x^{2} = \frac{π}{2} + 2 πn

对于

x^{2} = f (a)

解为

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

x = \frac{π}{2} + 2 πn, x = - \frac{π}{2} + 2 πn

化简

\frac{π}{2} + 2 πn : \frac{π + 4 πn}{2}

\frac{π}{2} + 2 πn

化简

\frac{π}{2} + 2 πn : \frac{π + 4 πn}{2}

\frac{π}{2} + 2 πn

将项转换为分式:

2 πn = \frac{2 πn 2}{2}

= \frac{π}{2} + \frac{2 πn \cdot 2}{2}

因为分母相等，所以合并分式:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{π + 2 πn \cdot 2}{2}

数字相乘:

2 \cdot 2 = 4

= \frac{π + 4 πn}{2}

= \frac{π + 4 πn}{2}

化简

- \frac{π}{2} + 2 πn : - \frac{π + 4 πn}{2}

- \frac{π}{2} + 2 πn

化简

\frac{π}{2} + 2 πn : \frac{π + 4 πn}{2}

\frac{π}{2} + 2 πn

将项转换为分式:

2 πn = \frac{2 πn 2}{2}

= \frac{π}{2} + \frac{2 πn \cdot 2}{2}

因为分母相等，所以合并分式:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{π + 2 πn \cdot 2}{2}

数字相乘:

2 \cdot 2 = 4

= \frac{π + 4 πn}{2}

= - \frac{π + 4 πn}{2}

x = \frac{π + 4 πn}{2}, x = - \frac{π + 4 πn}{2}

x = \frac{π + 4 πn}{2}, x = - \frac{π + 4 πn}{2}

cos(2θ)-sqrt(3)cos(θ)=0,0<= θ<2pi

cos (2 θ) - 3 cos (θ) = 0, 0 \leq θ < 2 π

2cos^2(θ)-7cos(θ)-4=0

2 cos^{2} (θ) - 7 cos (θ) - 4 = 0

sin(θ)= 3/10 ,sin(θ+pi/6)

sin (θ) = \frac{3}{10}, sin (θ + \frac{π}{6})

3sin^2(x)=8cos(x)

3 sin^{2} (x) = 8 cos (x)

7cos(x)-24sin(x)=10

7 cos (x) - 24 sin (x) = 10
