 Encyclopedia should be accessible to laymen, this article is not. 

 If I hadn't had a solid secondary school education, I would not understand a word of this explanation. This is not the place for specialized lingo, this is the free encyclopedia that should help especially those who were not blessed with, or could not afford to build, a strong math background. 

 Please re-write for the mainstream.
