受欢迎的三角函数 >

tan(x)= 12/6

解答

tan (x) = \frac{12}{6}

解答

x = 1.10714 \dots + πn

+1

度数

x = 63.43494 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (x) = \frac{12}{6}

数字相除:

\frac{12}{6} = 2

tan (x) = 2

使用反三角函数性质

tan (x) = 2

tan (x) = 2

的通解

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

x = arctan (2) + πn

x = arctan (2) + πn

以小数形式表示解

x = 1.10714 \dots + πn

流行的例子

1 - 2 tan (x) = 0

sin (a) = 0.747

1-tan^2(y)=2sec(y)-4

1 - tan^{2} (y) = 2 sec (y) - 4

3 cot (x) + 4 = 7

cot^2(x)csc^2(x)+2csc^2(x)-cot^2(x)=2

cot^{2} (x) csc^{2} (x) + 2 csc^{2} (x) - cot^{2} (x) = 2
