3tan(2x)-sqrt(3)=0

解答

3 tan (2 x) - 3 = 0

解答

x = \frac{π}{12} + \frac{πn}{2}

+1

度数

x = 1 5^{\circ} + 9 0^{\circ} n

求解步骤

3 tan (2 x) - 3 = 0

将

3

到右边

3 tan (2 x) - 3 = 0

两边加上

3

3 tan (2 x) - 3 + 3 = 0 + 3

化简

3 tan (2 x) = 3

3 tan (2 x) = 3

两边除以

3

3 tan (2 x) = 3

两边除以

3

\frac{3 tan ( 2 x )}{3} = \frac{3}{3}

化简

tan (2 x) = \frac{3}{3}

tan (2 x) = \frac{3}{3}

tan (2 x) = \frac{3}{3}

的通解

周期表（周期为

πn

）：

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

2 x = \frac{π}{6} + πn

2 x = \frac{π}{6} + πn

解

2 x = \frac{π}{6} + πn : x = \frac{π}{12} + \frac{πn}{2}

2 x = \frac{π}{6} + πn

两边除以

2

2 x = \frac{π}{6} + πn

两边除以

2

\frac{2 x}{2} = \frac{\frac{π}{6}}{2} + \frac{πn}{2}

化简

\frac{2 x}{2} = \frac{\frac{π}{6}}{2} + \frac{πn}{2}

化简

\frac{2 x}{2} : x

\frac{2 x}{2}

数字相除:

\frac{2}{2} = 1

= x

化简

\frac{\frac{π}{6}}{2} + \frac{πn}{2} : \frac{π}{12} + \frac{πn}{2}

\frac{\frac{π}{6}}{2} + \frac{πn}{2}

\frac{\frac{π}{6}}{2} = \frac{π}{12}

\frac{\frac{π}{6}}{2}

使用分式法则:

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

= \frac{π}{6 \cdot 2}

数字相乘:

6 \cdot 2 = 12

= \frac{π}{12}

= \frac{π}{12} + \frac{πn}{2}

x = \frac{π}{12} + \frac{πn}{2}

x = \frac{π}{12} + \frac{πn}{2}

x = \frac{π}{12} + \frac{πn}{2}

x = \frac{π}{12} + \frac{πn}{2}
