受欢迎的三角函数 >

tan(2θ)=0.55

解答

tan (2 θ) = 0.55

解答

θ = \frac{0.50284 \dots}{2} + \frac{πn}{2}

+1

度数

θ = 14.40539 \dots^{\circ} + 9 0^{\circ} n

求解步骤

tan (2 θ) = 0.55

使用反三角函数性质

tan (2 θ) = 0.55

tan (2 θ) = 0.55

的通解

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

2 θ = arctan (0.55) + πn

2 θ = arctan (0.55) + πn

解

2 θ = arctan (0.55) + πn : θ = \frac{arctan ( 0.55 )}{2} + \frac{πn}{2}

2 θ = arctan (0.55) + πn

两边除以

2

2 θ = arctan (0.55) + πn

两边除以

2

\frac{2 θ}{2} = \frac{arctan ( 0.55 )}{2} + \frac{πn}{2}

化简

θ = \frac{arctan ( 0.55 )}{2} + \frac{πn}{2}

θ = \frac{arctan ( 0.55 )}{2} + \frac{πn}{2}

θ = \frac{arctan ( 0.55 )}{2} + \frac{πn}{2}

以小数形式表示解

θ = \frac{0.50284 \dots}{2} + \frac{πn}{2}

35.35=100cos(x)

35.35 = 100 cos (x)

sin (θ) = - \frac{3}{8}

sin(2x-20)=-cos(3x+50)

sin (2 x - 20) = - cos (3 x + 50)

(sin(60))/(174.36)=(sin(x))/(200)

\frac{sin ( 6 0 ^{\circ} )}{174.36} = \frac{sin ( x )}{200}

cos (x) = \frac{8}{13}
