cot(θ)=0.8701

解答

cot (θ) = 0.8701

θ = 0.85474 \dots + πn

度数

θ = 48.97346 \dots^{\circ} + 18 0^{\circ} n

求解步骤

cot (θ) = 0.8701

使用反三角函数性质

cot (θ) = 0.8701

cot (θ) = 0.8701

的通解

cot (x) = a \Rightarrow x = arccot (a) + πn

θ = arccot (0.8701) + πn

θ = arccot (0.8701) + πn

以小数形式表示解

θ = 0.85474 \dots + πn

cos (x) = - 1 + \frac{576}{625}

2 sin (θ) cos (θ) - sin (θ) = sin (θ) cos (θ)

3 - \frac{1}{2} \cdot tan (θ) = \frac{6 + 3}{2}

5 sin (x) = 3, sin (x) + cos (x)

sin^{2} (3 x) + 2 sin (x) cos (x) + cos^{2} (3 x) = 0
