# Why do we have $C(u,v) = V_{C}([0,u]\times[0,v])$?
by user1337 Last Updated August 14, 2019 03:19 AM
Given that $$C:[0,1]\times[0,1]\rightarrow[0,1]$$ is a copula and $$V_{C}([0,u]\times[0,v])$$ is the $$C$$-volume of the rectangle $$[0,u]\times[0,v]$$, why $$C(u,v) = V_{C}([0,u]\times[0,v])$$?

# nLab Galois extension
Classically, “Galois extension” refers to a class of extensions of fields.
An extension $K\subset L$ of fields is Galois if it is normal and separable. In that case, the automorphism group $Aut_K(L)$ of $K$-automorphisms of $L$ is called the Galois group and often denoted by $Gal(L:K)$.

I tried with Google but I couldn't find anything, so here goes: When I "use ln on a quantity" (I don't really know how to phrase it in english, as we just have a verb for it), say, I have n = 0.00149 kg/m*s, and I put it into the ln, so now I have ln(0.00149... | {} |
# Peano's axioms for the Natural numbers
1. 1 is a natural number.
