Best ResponseYou've already chosen the best response.0no no The whole thing inside the integral is squared.

Best ResponseYou've already chosen the best response.0That's why I have a parentheses in the beginning it just doesn't show it that well when i used equations.

Best ResponseYou've already chosen the best response.0So do I just foil it out and find the integral?

Best ResponseYou've already chosen the best response.0If it really bothers you that much. I would just treat i as a constnat. Replace i with g and just integrate it like a constant.

Best ResponseYou've already chosen the best response.0Then, replace the g's back with i's. Remember that i^2=1

Best ResponseYou've already chosen the best response.0If I carry out the foil I know that I can split it into three different integral with the first one being integrating 1/3pi If I do that I can simply take out 1/3pi since it's a constant and I get (1/3pi)(2pi0)=2/3 which is the answer but how does that other part cancel out?

Best ResponseYou've already chosen the best response.0Oh I think I know what I did wrong. I was suppose to multiply the inside function with it's complex conjugate so it cancels out all imaginar values.

Best ResponseYou've already chosen the best response.0No the thing is that I was suppose to multiply imaginary function with imaginary and that just cancels out all the imaginaries.

Best ResponseYou've already chosen the best response.0Have you tried foiling that giant square and breaking up the integral and placing the e^ix before the integral?

Best ResponseYou've already chosen the best response.0Oh the web version works for free. Yeah, sometime you just gotta tinker with the input. I'm deleting the image links, but here is my mathy blog, FWIW http://mathstem.blogspot.com/ I'll delete my cell# too, lol!
