Formula

$\begin{array}{rl}{J}_{-(m+\frac{1}{2})}(x)& =(-1{)}^{m+1}{Y}_{m+\frac{1}{2}}(x),\\ Y_{-(m+\frac{1}{2})}(x)& =(-1{)}^m{J}_{m+\frac{1}{2}}(x).\end{array}$

TeX Source

\begin{align}J_{-(m+\frac{1}{2})}(x) &= (-1)^{m+1} Y_{m+\frac{1}{2}}(x), \\Y_{-(m+\frac{1}{2})}(x) &= (-1)^m J_{m+\frac{1}{2}}(x).\end{align}
