cot(θ)=0.75

解答

cot (θ) = 0.75

θ = 0.92729 \dots + πn

度数

θ = 53.13010 \dots^{\circ} + 18 0^{\circ} n

求解步骤

cot (θ) = 0.75

使用反三角函数性质

cot (θ) = 0.75

cot (θ) = 0.75

的通解

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

θ = arccot (0.75) + πn

θ = arccot (0.75) + πn

以小数形式表示解

θ = 0.92729 \dots + πn

6 sin (x) - 2 cos (x) = 2

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

cos (x) = \frac{60}{61}, tan (x) = \frac{11}{60}

32 cos (x) + 2 = - 1

4 = tan^{2} (4 5^{\circ} + \frac{x}{2})
