comment Semidirect Products with GAP
Thanks @JacobSchlather, I'll read those pages and post a solution if I can figure it out. Others are of course still welcome to help :)

comment What is the “standard basis” for fields of complex numbers?
@QiaochuYuan, yes, sorry, that wasn't a particularly relevant response!

comment Understanding the equivariant rank theorem
Wait, maybe this is a silly question. In the general case we know $T_pM$ and $T_{\varphi(p)}N$ have the same dimension, so we can just map the basis vectors for one bijectively to the basis vectors of the other?

comment How to show that derivative of $\phi(v)$ with respect to $v$ is $\phi'( v)= a(1-\phi^2(v))/2$
Write out the $\tanh$ function using exponentials and then try to get the above relations. Check the wikipedia article on hyperbolic trigonometric functions.

comment Matrix group as subgroup of $GL(n,\mathbb{R})$ or $GL(n,\mathbb{C}$)?
Perhaps not technical, but I much prefer $GL(n,\mathbb{R})\leq GL(n,\mathbb{C})$ simply because $\mathbb{C}$ is an extension of $\mathbb{R}$
