Re: Kx Ky Bullshit Dear brother, first of all, respect your brothers in the forum and people who are the age of your grandfather, express the title of the subject with words that would suit an engineer. With the street mouth, you are throwing in a right attitude as if people have to help you here. I wish you success in your education life. I'm sure if you write the name of the subject properly and express your problem in a way that befits a university student, even me, we will all help. Stay well.
