解答

展开

\frac{2 ( π + 180 )}{360}

\frac{π}{180 2} + \frac{1}{2}

十进制

0.71944 \dots

求解步骤

\frac{2 ( π + 180 )}{360}

乘开

2 (π + 180) : 2 π + 1802

= \frac{2 π + 180 2}{360}

使用分式法则:

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

\frac{2 π + 180 2}{360} = \frac{2 π}{360} + \frac{180 2}{360}

= \frac{2 π}{360} + \frac{180 2}{360}

\frac{2 π}{360} = \frac{π}{180 2}

\frac{180 2}{360} = \frac{1}{2}

= \frac{π}{180 2} + \frac{1}{2}
