受欢迎的三角函数 >

sin(4x+10)=sin(90)

解答

sin (4 x + 10) = sin (9 0^{\circ})

解答

x = - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

+1

弧度

x = - \frac{5}{2} + \frac{π}{8} + \frac{π}{2} n

求解步骤

sin (4 x + 10) = sin (9 0^{\circ})

sin (9 0^{\circ}) = 1

sin (9 0^{\circ})

使用以下普通恒等式:

sin (9 0^{\circ}) = 1

sin (9 0^{\circ})

sin (x)

4 x + 10 = 9 0^{\circ} + 36 0^{\circ} n

4 x + 10 = 9 0^{\circ} + 36 0^{\circ} n

解

4 x + 10 = 9 0^{\circ} + 36 0^{\circ} n : x = - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

4 x + 10 = 9 0^{\circ} + 36 0^{\circ} n

将

10

到右边

4 x + 10 = 9 0^{\circ} + 36 0^{\circ} n

两边减去

10

4 x + 10 - 10 = 9 0^{\circ} + 36 0^{\circ} n - 10

化简

4 x = 9 0^{\circ} + 36 0^{\circ} n - 10

4 x = 9 0^{\circ} + 36 0^{\circ} n - 10

两边除以

4

4 x = 9 0^{\circ} + 36 0^{\circ} n - 10

两边除以

4

\frac{4 x}{4} = \frac{9 0 ^{\circ}}{4} + \frac{36 0 ^{\circ} n}{4} - \frac{10}{4}

化简

\frac{4 x}{4} = \frac{9 0 ^{\circ}}{4} + \frac{36 0 ^{\circ} n}{4} - \frac{10}{4}

化简

\frac{4 x}{4} : x

\frac{4 x}{4}

数字相除:

\frac{4}{4} = 1

= x

化简

\frac{9 0 ^{\circ}}{4} + \frac{36 0 ^{\circ} n}{4} - \frac{10}{4} : - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

\frac{9 0 ^{\circ}}{4} + \frac{36 0 ^{\circ} n}{4} - \frac{10}{4}

对同类项分组

= - \frac{10}{4} + \frac{36 0 ^{\circ} n}{4} + \frac{9 0 ^{\circ}}{4}

\frac{10}{4} = \frac{5}{2}

\frac{10}{4}

约分:

2

= \frac{5}{2}

\frac{36 0 ^{\circ} n}{4} = \frac{18 0 ^{\circ} n}{2}

\frac{36 0 ^{\circ} n}{4}

约分:

2

= \frac{18 0 ^{\circ} n}{2}

\frac{9 0 ^{\circ}}{4} = 22. 5^{\circ}

\frac{9 0 ^{\circ}}{4}

使用分式法则:

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

= \frac{18 0 ^{\circ}}{2 \cdot 4}

数字相乘:

2 \cdot 4 = 8

= 22. 5^{\circ}

= - \frac{5}{2} + \frac{18 0 ^{\circ} n}{2} + 22. 5^{\circ}

对同类项分组

= - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

x = - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

x = - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}

x = - \frac{5}{2} + 22. 5^{\circ} + \frac{18 0 ^{\circ} n}{2}
