受欢迎的三角函数 >

34*sin(pi/6 (x-4.3))=34

解答

34 \cdot sin (\frac{π}{6} (x - 4.3)) = 34

解答

x = 12 n + 7.3

+1

度数

x = 418.25919 \dots^{\circ} + 687.54935 \dots^{\circ} n

求解步骤

34 sin (\frac{π}{6} (x - 4.3)) = 34

两边除以

34

34 sin (\frac{π}{6} (x - 4.3)) = 34

两边除以

34

\frac{34 sin ( \frac{π}{6} ( x - 4.3 ) )}{34} = \frac{34}{34}

化简

sin (\frac{π}{6} (x - 4.3)) = 1

sin (\frac{π}{6} (x - 4.3)) = 1

sin (\frac{π}{6} (x - 4.3)) = 1

\frac{π}{6} (x - 4.3) = \frac{π}{2} + 2 πn

\frac{π}{6} (x - 4.3) = \frac{π}{2} + 2 πn

解

\frac{π}{6} (x - 4.3) = \frac{π}{2} + 2 πn : x = 12 n + 7.3

\frac{π}{6} (x - 4.3) = \frac{π}{2} + 2 πn

在两边乘以

6

\frac{π}{6} (x - 4.3) = \frac{π}{2} + 2 πn

在两边乘以

6

6 \cdot \frac{π}{6} (x - 4.3) = 6 \cdot \frac{π}{2} + 6 \cdot 2 πn

化简

6 \cdot \frac{π}{6} (x - 4.3) = 6 \cdot \frac{π}{2} + 6 \cdot 2 πn

化简

6 \cdot \frac{π}{6} (x - 4.3) : π (x - 4.3)

6 \cdot \frac{π}{6} (x - 4.3)

分式相乘:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{6 π}{6} (x - 4.3)

约分:

6

= (x - 4.3) π

化简

6 \cdot \frac{π}{2} + 6 \cdot 2 πn : 3 π + 12 πn

6 \cdot \frac{π}{2} + 6 \cdot 2 πn

6 \cdot \frac{π}{2} = 3 π

6 \cdot \frac{π}{2}

分式相乘:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 6}{2}

数字相除:

\frac{6}{2} = 3

= 3 π

6 \cdot 2 πn = 12 πn

6 \cdot 2 πn

数字相乘:

6 \cdot 2 = 12

= 12 πn

= 3 π + 12 πn

π (x - 4.3) = 3 π + 12 πn

π (x - 4.3) = 3 π + 12 πn

π (x - 4.3) = 3 π + 12 πn

两边除以

π

π (x - 4.3) = 3 π + 12 πn

两边除以

= 3 + \frac{12 πn}{π}

消掉

\frac{12 πn}{π} : 12 n

\frac{12 πn}{π}

约分:

π

= 12 n

= 3 + 12 n

x - 4.3 = 3 + 12 n

x - 4.3 = 3 + 12 n

x - 4.3 = 3 + 12 n

将

4.3

到右边

x - 4.3 = 3 + 12 n

两边加上

4.3

x - 4.3 + 4.3 = 3 + 12 n + 4.3

化简

x = 12 n + 7.3

x = 12 n + 7.3

x = 12 n + 7.3

2(sin(x))2-5cos(x)-4=0

2 (sin (x)) 2 - 5 cos (x) - 4 = 0

cos(x/2+20)=sin(x)

cos (\frac{x}{2} + 2 0^{\circ}) = sin (x)

0=cos^2(x)+sin^2(x)-2sin(x),0<= x<= 2pi

0 = cos^{2} (x) + sin^{2} (x) - 2 sin (x), 0 \leq x \leq 2 π

sin (θ) = - \frac{7}{25}, sin (2 θ)
