受欢迎的三角函数 >

sin(θ)=(0.000069)2(500*10^{-9})

解答

sin (θ) = (0.000069) 2 (500 \cdot 1 0^{- 9})

解答

θ = 0 + 2 πn, θ = π - 0 + 2 πn

+1

弧度

θ = 0 + 2 πn, θ = π + 2 πn

求解步骤

sin (θ) = (0.000069) \cdot 2 (500 \cdot 1 0^{- 9})

化简

0.000069 \cdot 2 \cdot 500 \cdot 1 0^{- 9} : \frac{0.000069}{1000000}

0.000069 \cdot 2 \cdot 500 \cdot 1 0^{- 9}

使用指数法则:

a^{- b} = \frac{1}{a ^{b}}

1 0^{- 9} = \frac{1}{1 0 ^{9}}

= 2 \cdot 500 \cdot 0.000069 \cdot \frac{1}{1 0 ^{9}}

分式相乘:

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

= 0.000069 \cdot \frac{1 \cdot 2 \cdot 500}{1 0 ^{9}}

\frac{1 \cdot 2 \cdot 500}{1 0 ^{9}} = \frac{1}{1000000}

\frac{1 \cdot 2 \cdot 500}{1 0 ^{9}}

数字相乘:

1 \cdot 2 \cdot 500 = 1000

= \frac{1000}{1 0 ^{9}}

分解

1000 : 2^{3} \cdot 5^{3}

因式分解

1000 = 2^{3} \cdot 5^{3}

分解

1 0^{9} : 2^{9} \cdot 5^{9}

因式分解

10 = 2 \cdot 5

= (2 \cdot 5)^{9}

使用指数法则:

(ab)^{c} = a^{c} b^{c}

= 2^{9} \cdot 5^{9}

= \frac{2 ^{3} \cdot 5 ^{3}}{2 ^{9} \cdot 5 ^{9}}

消掉

\frac{2 ^{3} \cdot 5 ^{3}}{2 ^{9} \cdot 5 ^{9}} : \frac{1}{2 ^{6} \cdot 5 ^{6}}

\frac{2 ^{3} \cdot 5 ^{3}}{2 ^{9} \cdot 5 ^{9}}

使用指数法则:

\frac{x ^{a}}{x ^{b}} = \frac{1}{x ^{b - a}}

\frac{2 ^{3}}{2 ^{9}} = \frac{1}{2 ^{9 - 3}}

= \frac{5 ^{3}}{5 ^{9} \cdot 2 ^{9 - 3}}

数字相减:

9 - 3 = 6

= \frac{5 ^{3}}{5 ^{9} \cdot 2 ^{6}}

使用指数法则:

\frac{x ^{a}}{x ^{b}} = \frac{1}{x ^{b - a}}

\frac{5 ^{3}}{5 ^{9}} = \frac{1}{5 ^{9 - 3}}

= \frac{1}{2 ^{6} \cdot 5 ^{9 - 3}}

数字相减:

9 - 3 = 6

= \frac{1}{2 ^{6} \cdot 5 ^{6}}

= \frac{1}{2 ^{6} \cdot 5 ^{6}}

2^{6} \cdot 5^{6} = 1000000

2^{6} \cdot 5^{6}

2^{6} = 64

= 5^{6} \cdot 64

5^{6} = 15625

= 64 \cdot 15625

数字相乘:

64 \cdot 15625 = 1000000

= 1000000

= \frac{1}{1000000}

= 0.000069 \cdot \frac{1}{1000000}

分式相乘:

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

= \frac{1 \cdot 0.000069}{1000000}

数字相乘:

1 \cdot 0.000069 = 0.000069

= \frac{0.000069}{1000000}

使用反三角函数性质

sin (θ) = \frac{0.000069}{1000000}

sin (θ) = \frac{0.000069}{1000000}

的通解

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

θ = arcsin (\frac{0.000069}{1000000}) + 2 πn, θ = π - arcsin (\frac{0.000069}{1000000}) + 2 πn

θ = arcsin (\frac{0.000069}{1000000}) + 2 πn, θ = π - arcsin (\frac{0.000069}{1000000}) + 2 πn

以小数形式表示解

θ = 0 + 2 πn, θ = π - 0 + 2 πn
