I have been being confused by mathematics’ formula which are not so familiar with me before. Reading a mathematics’  book is not like reading  such kind of comics of Naruto or novel of Sidney Sheldon. I decided to sort it and copied paste into my blog therefore i can always remember although  it is not often used regularly. Might be it would be useful for someone outside there, who are studying and dealing with Engineerings’ area.
