hi all, i've tried to solve this thing with Derive, but it gave me some vague erf(x) function (error function??). Is there some gosu-mathematician who can help me solve the integral? [tex] \int exp(-x^2) dx [/tex] tnx
There is no analytic form to the gaussian integral. You need to look up values in the erf table for definite integrals.
Tom did this using double integration here: https://www.physicsforums.com/showthread.php?t=25798&page=2 Have fun!
It's the limits of integration that count here. Say you're trying to integrate a hard function, but there's a neat little trick for working out the integral from zero to infinity. That trick probably won't help you if you're integrating from, say, 1 to 5.729.
When I first did that integral (the trick way with the nice limits) I thought it was the neatest thing.
integrate exp(-(x/C)^k), dx with k>0 and C>0 Hello to you all, i've tried hard to solve this problem related with the wind resources, but so far like Tom Mattson said in is post, i solved the problem to k=2, but i can't solve it to any k>0!!! integrate exp(-(x/C)^k), dx with k>0 and C>0 Is there anyone willing to help me ???? Perinhas.
