\frac{t ^{2}}{2} = \frac{3 π}{2} + 2 πn

\frac{t ^{2}}{2} = \frac{3 π}{2} + 2 πn

解

\frac{t ^{2}}{2} = \frac{3 π}{2} + 2 πn : t = 3 π + 4 πn, t = - 3 π + 4 πn

\frac{t ^{2}}{2} = \frac{3 π}{2} + 2 πn

在两边乘以

2

\frac{t ^{2}}{2} = \frac{3 π}{2} + 2 πn

在两边乘以

2

\frac{2 t ^{2}}{2} = 2 \cdot \frac{3 π}{2} + 2 \cdot 2 πn

化简

\frac{2 t ^{2}}{2} = 2 \cdot \frac{3 π}{2} + 2 \cdot 2 πn

化简

\frac{2 t ^{2}}{2} : t^{2}

\frac{2 t ^{2}}{2}

数字相除:

\frac{2}{2} = 1

= t^{2}

化简

2 \cdot \frac{3 π}{2} + 2 \cdot 2 πn : 3 π + 4 πn

2 \cdot \frac{3 π}{2} + 2 \cdot 2 πn

2 \cdot \frac{3 π}{2} = 3 π

2 \cdot \frac{3 π}{2}

分式相乘:

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

= \frac{3 π 2}{2}

约分:

2

= 3 π

2 \cdot 2 πn = 4 πn

2 \cdot 2 πn

数字相乘:

2 \cdot 2 = 4

= 4 πn

= 3 π + 4 πn

t^{2} = 3 π + 4 πn

t^{2} = 3 π + 4 πn

t^{2} = 3 π + 4 πn

对于

x^{2} = f (a)

解为

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

t = 3 π + 4 πn, t = - 3 π + 4 πn

t = 3 π + 4 πn, t = - 3 π + 4 πn
