How can I expand this expression $(1-x^2)^-5/2$ as a series in x?



I'm looking eventually for a series in $x_1$ and $x_2$ where $x$, $x_1$, and $x_2$ are magnitudes of $vecx$,$vecx_1$, and $vecx_2$ and $vecx$ = $vecx_1$ + $vecx_2$

    Do you know how to expand $(1-y)^-5/2?$. You can do that with the binomial theorem. Now set $y=x^2$

  • Please correct me: $(1-x^2)^-5/2 = 1 +frac52x^2 + frac358x^4+frac10516x^6$
