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

解答

tan (x) = - 3 + 2

x = 0.26179 \dots + πn

度数

x = 1 5^{\circ} + 18 0^{\circ} n

求解步骤

tan (x) = - 3 + 2

使用反三角函数性质

tan (x) = - 3 + 2

tan (x) = - 3 + 2

的通解

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (- 3 + 2) + πn

x = arctan (- 3 + 2) + πn

以小数形式表示解

x = 0.26179 \dots + πn

3 tan (x) - cot (x) = 0

sin^{2} (x) = \frac{( 2 m - 1 )}{4}

cos (2 x) - 0.25 = 0

2 tan^{2} (x) + 1 = cos (x)

sec (x) = - \frac{4}{3}
