warning: exceedingly nerdy post.
i realized today that i am still as much of a math geek as i ever was. i had this exchange at work:
(upon returning to my office from filing something)
clerk: were you a math major as your undergrad?
me: yes, why?
clerk: a judge was in here looking for the math major
me: which judge?
clerk: mcvey? gray haired judge?
(i go and find the judge down the hall)
me: our clerk said you were looking for me?
judge: yes. do you know if there is an antiderivative for one over one plus x squared?
me: oh gosh, it's been a really long time. i can't think of it off the top of my head. you would probably do a trig substitution. probably (pause) tangent.
judge: okay thanks, i'll try that.
i went back to my office and was intrigued at this point, of course i had to try it out. also, just as i walked into my office, audrey called, so i confirmed with her that this would be the desired method. after hanging up with her, i sat down at my desk, and within 30 seconds had the solution* (for those of you who want to try this out on your own, i will post the answer at the bottom so that i don't ruin it for you). it was way too elating for me to consider myself normal anymore (not that i really did before).
i quickly ran upstairs to the judge's office, but he was meeting with someone in chambers, so i gave it to his clerk. i didn't get to inquire as to why he wanted to know such a thing and am sad that i didn't ask him during our face-to-face encounter. curious...
it's nice to know that after all these years, i've still got it.
