tan(x)= 35/29

解答

tan (x) = \frac{35}{29}

x = 0.87887 \dots + πn

度数

x = 50.35582 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (x) = \frac{35}{29}

使用反三角函数性质

tan (x) = \frac{35}{29}

tan (x) = \frac{35}{29}

的通解

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

x = arctan (\frac{35}{29}) + πn

x = arctan (\frac{35}{29}) + πn

以小数形式表示解

x = 0.87887 \dots + πn

3 sin (θ) = 1 - sin (θ)

1 = sin (9 0^{\circ} - θ) - 0.075 cos (9 0^{\circ} - θ)

- 6 sin (θ) = - 32

cos (x) = \frac{4 ( \frac{1}{2} ) - 1}{3}

sin (x) = \frac{π}{4} + \frac{0 π}{2}
