@kouba01 Dear professor, I am not stealing others content.

since I didn't consider rewriting a formula or arithmetic to be plagiarism and this isn't the first time I've made this kind of essay.

I have solid proof on it. But I do not want to point out every single line of the lecture as you have made your own research and deliver us a to the point lecture. Lecture is very useful for all of us but that does not mean that it was pure and use calculation other than standards. Thanks
