Random Math Question - 12/10/2007 10:20:39 PM

I realize this probably is the worst place in the world to ask this, but I'm out of time and, at this point, just curious. As it's on a test, please, no answers.. I'm just curious if this even exists to human knowledge.

The integal of (c^2/e^(2c^2kt)-1)^.5 with respect to t.. is there any way to integrate that without resorting to the damn hypergeometric functions?

So far, my best answer is from http://integrals.wolfram.com/index.jsp. But, honestly.. "0.---"?

Gah. This is what I get for not taking any Math classes lately. But, seriously, what the hell is my professor thinking, putting this on a timed test?

[/rant]

PS- This is due tommorow before noon. If anyone does, by some freakish chance, actually have a solution to this, I'd be interested in seeing it past such a time.

Also, this is a Physics problem. I was just solving it directly. It's entirely possible (actually, looking at this integral, practically certain) that there's another another way of solving this problem which doesn't involve the integrals from hell. I'm just ranting out of frustration and, well, let's face it.. I'm just curious if this integral's do-able since I can't seem to.

You are solving for t ? Fuck Man, just do it the hard way. I fell down on this shit along time ago.

Really, it looks like you are just going to have to do it the hard way.

Best of luck.

I hate to say it, but my highest education in Math stops just after Linear and Diffy Q; this is beyond my skill. If there was more time, I'm sure I could research them and figure it out, but, well.. I guess there just isn't.

It's okay, though. I figured out another way of doing the problem that is a lot easier. (Even if "easier" is purely relative.) I guess I'm just curious now if there is a good way of doing that thing.

I've had some pretty well educated individuals drop me a line from time to time. Hoping a Ph.D. with some insight on this subject might take pity. ;)

Welcome (back?) to college. The puking's entirely normal.

Freaking 6:11 AM, and I'm finally getting to bed for the one to two hours of napping I get before the next major exam. Blah.

Whining can be stress relieving, apparently. In any case, peace all; have a good week.

IIRC, I have't integrated anything that complex in a long time, yes you need the hypergeometric functions. That and a lot of aspirin. or one of those really good calculators that handles this sort of thing for you.

my only thought is you didn't spell check the OP...'cause you forgot an r in integral...other than that, i can't understand mathmatic equations without seeing them handwritten...my brain does not computer typed equations, just can't do it...i am like a record skipping a quarter of the way into the second line...
