Nothing enlightening in this post, or even informative. Just the overwhelming need to complain about my own stupidity.(adsbygoogle = window.adsbygoogle || []).push({});

I've been staring at this integral all day:

[tex]

\int_{-\infty}^{\infty} f(x)^{n-1} f'(x) dx

[/tex]

*sigh*

It doesn't dawn on me that this is a simple u-substitution until the drive home after a nice bridge session. Admittedly,fwasn't something with which I was eminently familiar -- it was [itex]1 + \mathop{erf} (x / \sqrt{2})[/itex], but still, there's no excuse!

But it gets worse. While I was working out how to set up the integral, I had already deduced the key step that would allow me to set up an easily solved recursive formula for my integral. I enjoy solving things with recursion. But did this dawn on me? Noooo... not until my drive home tonight.

*sigh*

But wait, my stupidity doesn't even end there! Before I was even interested in setting up and solving this integral, I hadalready figured outhow the value behaves asngrows! (And the behavior as I adjustnwas my primary interest)

But do I remember that? Nooo... not until the drive home today.

*sigh*

Sorry I took up so much space for this rant!
