How to find generators in $U(n)$? - Mathematics Stack Exchange
2017年11月12日 · Your question is kind of ambiguous as it's been worded currently, but I assume that you're asking about the generators of $\mathrm{U}(n)$, i.e. the group of elements of $\mathbb{Z_n}$ that have a multiplicative inverse.
How do we calculate factorials for numbers with decimal places?
I was playing with my calculator when I tried $1.5!$. It came out to be $1.32934038817$. Now my question is that isn't factorial for natural numbers only? Like $2!$ is $2\\times1$, but how do we e...

Calculating the Order of An Element in A Group
A group can have finite or infinite number of elements. When the group has finite number of elements, we see the least POSITIVE n i.e.(n>0) such that g^n gives the identity of the group (in case of multiplication) or n*g gives the identity (in case of addition).

Difference between "≈", "≃", and "≅" - Mathematics Stack Exchange
In my work "=" is the identity of a number so it states an equivalence. 1=1, 2x=10 ie x =5. The approximation sign "≈" I use for decimal approximations with tilde "~" being a rougher approximation.
