Prove J(-m) = [(-1)^m][J(m)]
(Note: by "J(-m)" I mean "subscript (-m)")
J(-m) = sum [((-1)^n) * (x/2)^(2n-m)]/[n! [tex]\Gamma[/tex](n - m + 1)]
J(m) should be obvious.
The Attempt at a Solution
I tried just plugging in the above formulas hoping to get a simplified answer, but I know I'm missing something in that denominator.
