Hi lucik1900;

What is x2? Is that x^2?


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Yes, it is, but I have noticed that people often use that kind of notation when they do not know how to put an exponent in the superscript.
