tan(θ)= 34400/254

解答

tan (θ) = \frac{34400}{254}

θ = 1.56341 \dots + πn

度数

θ = 89.57695 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (θ) = \frac{34400}{254}

tan (θ) = \frac{17200}{127}

使用反三角函数性质

tan (θ) = \frac{17200}{127}

tan (θ) = \frac{17200}{127}

的通解

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

θ = arctan (\frac{17200}{127}) + πn

θ = arctan (\frac{17200}{127}) + πn

以小数形式表示解

θ = 1.56341 \dots + πn

2 sin (x) = - 1, - π \leq x \leq π

cot (- \frac{π}{5}) - sec (x) = 1.5

\frac{1}{cos ^{2} ( x )} + (\frac{1}{2 cos ( x )}) = 0

cos (α) = \frac{1 + \frac{1}{5}}{2}

(tan (x)) (sin^{2} (x) - a) (sec (x) - a) = 0, 0 < a < 1
