受欢迎的三角函数 >

tan(x)= 2/8

解答

tan (x) = \frac{2}{8}

解答

x = 0.24497 \dots + πn

+1

度数

x = 14.03624 \dots^{\circ} + 18 0^{\circ} n

求解步骤

tan (x) = \frac{2}{8}

约分:

2

tan (x) = \frac{1}{4}

使用反三角函数性质

tan (x) = \frac{1}{4}

tan (x) = \frac{1}{4}

的通解

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

x = arctan (\frac{1}{4}) + πn

x = arctan (\frac{1}{4}) + πn

以小数形式表示解

x = 0.24497 \dots + πn

sec^2(x)tan(x)=2tan(x)

sec^{2} (x) tan (x) = 2 tan (x)

solvefor y,arctan(y)+1/2 (1-t)^2=c

so l v e f or y, arctan (y) + \frac{1}{2} (1 - t)^{2} = c

(15-sqrt(3))/3 =5-2/3*csc(4x+pi/2)

\frac{15 - 3}{3} = 5 - \frac{2}{3} \cdot csc (4 x + \frac{π}{2})

tan(x)+4sin(x)=0

tan (x) + 4 sin (x) = 0

1 + 2 \cdot sin (x) = 2
