受欢迎的三角函数 >

4.03sin(2pi)((200-76)/(365))+11.43

解答

4.03 sin (2 π) (\frac{200 - 76}{365}) + 11.43

解答

\frac{1143}{100}

+1

十进制

11.43

求解步骤

4.03 sin (2 π) (\frac{200 - 76}{365}) + 11.43

= \frac{403}{100} sin (2 π) \frac{200 - 76}{365} + \frac{1143}{100}

使用三角恒等式改写:

sin (2 π) = 0

sin (2 π)

sin (2 π) = sin (0)

sin (2 π)

将

2 π

改写为

2 π + 0

= sin (2 π + 0)

使用周期

sin

:

sin (x + 2 π) = sin (x)

sin (2 π + 0) = sin (0)

= sin (0)

= sin (0)

使用以下普通恒等式:

sin (0) = 0

sin (0)

sin (x)

= 0

= 0

= \frac{403}{100} \cdot 0 \cdot \frac{200 - 76}{365} + \frac{1143}{100}

化简

\frac{403}{100} \cdot 0 \cdot \frac{200 - 76}{365} + \frac{1143}{100} : \frac{1143}{100}

\frac{403}{100} \cdot 0 \cdot \frac{200 - 76}{365} + \frac{1143}{100}

\frac{403}{100} \cdot 0 \cdot \frac{200 - 76}{365} = 0

\frac{403}{100} \cdot 0 \cdot \frac{200 - 76}{365}

数字相减:

200 - 76 = 124

= 0 \cdot \frac{403}{100} \cdot \frac{124}{365}

分式相乘:

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

= 0 \cdot \frac{403 \cdot 124}{100 \cdot 365}

\frac{403 \cdot 124}{100 \cdot 365} = \frac{12493}{9125}

\frac{403 \cdot 124}{100 \cdot 365}

数字相乘:

403 \cdot 124 = 49972

= \frac{49972}{100 \cdot 365}

数字相乘:

100 \cdot 365 = 36500

= \frac{49972}{36500}

约分:

4

= \frac{12493}{9125}

= 0 \cdot \frac{12493}{9125}

使用法则

0 \cdot a = 0

= 0

= 0 + \frac{1143}{100}

0 + \frac{1143}{100} = \frac{1143}{100}

= \frac{1143}{100}

= \frac{1143}{100}
