受欢迎的三角函数 >

tan(x-1)=2

解答

tan (x - 1) = 2

解答

x = 1.10714 \dots + πn + 1

+1

度数

x = 120.73072 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (x - 1) = 2

使用反三角函数性质

tan (x - 1) = 2

tan (x - 1) = 2

的通解

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

x - 1 = arctan (2) + πn

x - 1 = arctan (2) + πn

解

x - 1 = arctan (2) + πn : x = arctan (2) + πn + 1

x - 1 = arctan (2) + πn

将

1

到右边

x - 1 = arctan (2) + πn

两边加上

1

x - 1 + 1 = arctan (2) + πn + 1

化简

x = arctan (2) + πn + 1

x = arctan (2) + πn + 1

x = arctan (2) + πn + 1

以小数形式表示解

x = 1.10714 \dots + πn + 1

5sin^2(x)+10sin(x)+2=0

5 sin^{2} (x) + 10 sin (x) + 2 = 0

tan(x)= 5/(5.1)

tan (x) = \frac{5}{5.1}

(sin(x))/(120)=(sin(60))/(300)

\frac{sin ( x )}{120} = \frac{sin ( 6 0 ^{\circ} )}{300}

8sin(θ)+15cos(θ)=0

8 sin (θ) + 15 cos (θ) = 0

sin (t) = \frac{3}{7}
