化简

\frac{3 csc ( \frac{π}{2} x )}{3} : csc (\frac{π}{2} x)

\frac{3 csc ( \frac{π}{2} x )}{3}

约分:

3

= csc (\frac{π}{2} x)

化简

\frac{2}{3} : \frac{2 3}{3}

\frac{2}{3}

乘以共轭根式

\frac{3}{3}

= \frac{2 3}{3 3}

33 = 3

33

使用根式运算法则:

a a = a

33 = 3

= 3

= \frac{2 3}{3}

csc (\frac{π}{2} x) = \frac{2 3}{3}

csc (\frac{π}{2} x) = \frac{2 3}{3}

csc (\frac{π}{2} x) = \frac{2 3}{3}
