comment Quotient Modules of finite rank module
Define $f: M \rightarrow M/T$ by $f(m)=2m+T$ if $m\in S$ and $f(m)=m+T$ if $m \in M \backslash S$, then we have $f$ is a homomorphism with $ker(f)=S$, so $M/S$ and $M/T$ are isomorphic.

@Sehmus: But the argument is based on graphic, not the mathematical argument?

SO your argument using taylor(MacLaurin) expansion is not true in general right?

I also try $X=(1, 1.1 ,1.2,...,5)$ and $Z=(z_i)$ with $z_i=e^{x_i}$ and we get $\rho(X,Z)=0.89$. How come?

Could you give any reference about this material?

In other word, correlation betwen X and Y tend to 1 but $y_i=x_i^2$ is not linear? How come?

comment Lebesgue-Stiletjes measure on $\mathbb{R}^2$
I mean $p(\cup (a_i,b_i] \times (c_i,d_i]) = \sum p ((a_i,b_i] \times (c_i,d_i])$

@anon271828, : Part (a), i just wanna make sure that is correct, but part (b) i have no idea. Any Hint?
