tan(θ)=-1.732

解答

tan (θ) = - 1.732

θ = - 1.04718 \dots + πn

度数

θ = - 59.99927 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (θ) = - 1.732

使用反三角函数性质

tan (θ) = - 1.732

tan (θ) = - 1.732

的通解

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

θ = arctan (- 1.732) + πn

θ = arctan (- 1.732) + πn

以小数形式表示解

θ = - 1.04718 \dots + πn

sin (\frac{θ}{2}) + cos (θ) = 0

4 cos (x) = 2 sin (x)

(6 cos (x) - 5 sin (x))^{2} + 11 sin^{2} (x) = 36

(3 cos (x) - 6 sin (x))^{2} - 27 sin^{2} (x) = - 9

3 (cos (x) - sin (x)) = 0
