comment Resources to learn the meaning of any math symbol
@Hagen - I guess Adrián saw it in the document referred to in this answer. Unfortunately this assumes a rather advanced level from the reader, and familiarity with notation, so symbols and operators aren't explained there.

comment Steps to Re-Learn Mathematic the right way
You don't want a "complete guide". Today's mathematics covers so many areas that the complete guide wouldn't fit on your bookshelf, let alone that you would have the means to absorb all of it: that's time, and mental capacity. No offense: nobody understands everything in mathematics. It would be a good idea if you would indicate what application of your maths you have in mind.

comment Prove $ \sqrt{\arctan(x)} = (1/2) \arccos((1-x)/(1+x))$
This statement is not true: Sqrt[ArcTan[x]] === 1/2 ArcCos[(1 - x)/(1 + x)] --> False. Can anybody check if my TeX-ification is correct?

This looks like a math problem, nothing to do with Mathematica. Migrate?
