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.

Re: Derivative

Why are the exponents still in there after you put it in radicals?/

Re: Derivative

The exponents are powers of x.
