Hey, what's up?
I'm wondering if anyone in this sub-forum actually works on High Energy particles. I want to know if you can introduce me on this matter (yes I know I can read Wikipedia and a ton of book but I want to have the word of a expert in this matter). I'd be glad if you can tell me...
Hey, I'm on my mobile right now so I can't see your proves for first and four integrals but for the second and third use simple fractions. I mean, you have the denominator
a^2 - x^2 = (a+x)(a-x)
So you can write
1/(a^2 - x^2) = 1/((a+x)(a-x)) = A/(a+x) + B/(a-x)
For some constants A, B...
