New Tag [Unofficial Skripsi Advisor]

Following the new semester, I have some of my junior working on their undergraduate thesis (so called skripsi) with me, since I cannot come to campus quite often, I'm planning to direct them on their skripsi via this blog (LaTex would help).  

The tag is [Unofficial Skripsi Advisor] and will be indicated on its title post by  abbreviation [UnSA]. 

The proofs that will be presented might also being found on the books. But, it will be described in detail. Also, some proofs might be also a new proof based on recent Journal (if it is more elementary than the already known proof).
