受欢迎的三角函数 >

cot(θ-pi/2)=1.07

解答

cot (θ - \frac{π}{2}) = 1.07

解答

θ = 0.75159 \dots + πn + \frac{π}{2}

+1

度数

θ = 133.06319 \dots^{\circ} + 18 0^{\circ} n

求解步骤

cot (θ - \frac{π}{2}) = 1.07

使用反三角函数性质

cot (θ - \frac{π}{2}) = 1.07

cot (θ - \frac{π}{2}) = 1.07

的通解

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

θ - \frac{π}{2} = arccot (1.07) + πn

θ - \frac{π}{2} = arccot (1.07) + πn

解

θ - \frac{π}{2} = arccot (1.07) + πn : θ = arccot (1.07) + πn + \frac{π}{2}

θ - \frac{π}{2} = arccot (1.07) + πn

将

\frac{π}{2}

到右边

θ - \frac{π}{2} = arccot (1.07) + πn

两边加上

\frac{π}{2}

θ - \frac{π}{2} + \frac{π}{2} = arccot (1.07) + πn + \frac{π}{2}

化简

θ = arccot (1.07) + πn + \frac{π}{2}

θ = arccot (1.07) + πn + \frac{π}{2}

θ = arccot (1.07) + πn + \frac{π}{2}

以小数形式表示解

θ = 0.75159 \dots + πn + \frac{π}{2}
