From my point of view, Wikipedia does not explain some topics well. Even though they are correct and completed, they are hard to understand. I try to make them simply to understand by outlining the main points.

Originally, I was wrong about the convergence. I thought functions always converge to their fixed points. However, it is not true for all functions. The convergence dependences on the slopes of functions. The functions with positive slopes are going to converge to their fixed points and the functions with negative slopes are not going to converge.

On my page, I outline the definition of fixed point, the three cases of fixed point, and the convergence with different slopes of functions. These are what the fixed point is, how to find it and how it works. I believe, these basic information will give people the brief understanding of the fixed point.
