comment Tensor Product of Spaces has Basis of Tensor Products
Yea the first is trivial since we are spanning all the possible basis combinations, so for linear independence its not clear how to exploit linearity for the proof

comment Why isn't finite calculus more popular?
The challenge here is that unless $h=0$ or some function that is known to cancel out with the difference g, then you end up having to recursively work with sub-difference equations, in order to say make a change variables (like a u subsitution) etc... that being said it is doable with enough machinery built up

Let $D_{h,x}(f) = \frac{f(x+h)-f(x)}{h}$ then $D_{h,x}(f(g)) = D_{h,x}(g) D_{h*D_{h,x}(g),g}(f(g))$

@AkivaWeinberger false, it does have a very obscure chain rule, but it is significantly trickier to use

comment How many ways are there to choose one-half dozen donuts from $9$ varieties so that there are exactly $4$ glazed?
Welcome to Math.SE! please show what you have tried on the problem, so we can accordingly help. Even if it didn't work, showing your analysis is very helpful for people answering and future users of the site

comment Is $S_1\cap S_2$ and $S_1\setminus S_2$ always linearly dependent if $S_1$ and $S_2$ are linearly dependent subsets of vector space $V$?
Your second counterexample $S_2$ is wrong since you can't have a single vector be linearly dependent (unless that is the 0 vector). That said you are close to correct, just pick bigger sets of vectors for $S_1$ and $S_2$

Is the intersection and intersection of generated spaces or just a regular ol' set intersection?

It isn't clear to me why the absolute value is necessary, please enlighten me :)
