    How do I solve the integral of exp(-x^2) between -a and a?

    The thing is, the integral of the whole expression is supposed to divide out to 1. The integral is supposed to end up being the inverse of the constant you pull out when you integrate, giving you a 1/1 or 1 answer. This suggests that standard integration techniques won't work, because the when...

    How do I solve the integral of exp(-x^2) between -a and a?

    hmmm... Yeah, those were the methods that I used to integrate it, integration by parts, substitution, and taking the limit. I talked to my Calculus 3 teacher yesterday about it, and she said it was something like a complex integral where you can't just solve it using those methods...or...

    How do I solve the integral of exp(-x^2) between -a and a?

    Ooops, sorry. The integration is from zero to infinity. I'll type in what I've done so far if someone can tell me how to get the integral and various other mathematical characters in the post, it's much easier that way. But so far my methods have included substitution, integration by parts, and...

    How do I solve the integral of exp(-x^2) between -a and a?

    Could someone show me how the integral of f(v) equals 1, where f(v) is (4/(Sqrt Pi)) x (m/2kT)^(3/2) x (v^2) x (e^(-mv^2/2kT)) I got through the integral and it didn't equal 1, but it's supposed to, so could someone help me out.

    Time Dilation different depending on cause?

    My question concerns gravitational time dilation and time time dilation due to motion. If an outside observer views a person falling into a black hole to stand still when the person falling into the event horizon due to time standing still at the horizon, then why don't particle physicists view...

    Does mass truly increase with energy according to special relativity?

    hmmm... I saw that quote from Einstein the other day and was wondering sort of the same thing.

    Time Dilation of Stationary Photons

    hmmm... Ohhh, I see. Since time doesn't exist for the photon, but how would time dilation effect it's motion as viewed by an observer. I've read of many examples of where an object such a person falls into a black hole and experiences time dilation so severe that an onlooker would see the...

    Time Dilation of Stationary Photons

    I know that the speed of light is constant no matter the speed of the observer, my question deals with the effects of time dilation on a photon moving at light speed. A photon at light speed would experience 100 percent time dilation due to it's velocity, therefore, shouldn't it appear...

    Does mass truly increase with energy according to special relativity?

    The first of my two questions concerns the aspect of SR that deals with the mass of an object increasing as is moves faster and faster (or more appropriately, as the energy gets larger and larger). I'm a novice when it comes to higher level physics, and everything I know comes from reading books...
