comment I need help with doing two inductive proofs using integration by parts.
@user190080 : If you want to clean up the MathJax usage, then the following isn't a really great place to leave it: $\int_0^{pi/2} \sin^{2n - 1}(x)dx = \frac{2*4*6***2n}{3*5*7***(2n + 1)}$. I changed it to this: $$\int_0^{pi/2} \sin^{2n - 1}x \, dx = \frac{2\cdot4\cdot6\cdots2n}{3\cdot5\cdot7\cdots(2n + 1)}$$ Note $\pi$ rather than $pi$ and $\text{“}\cdots\text{''}$ rather than $\text{“}***\text{''}$. Using an asterisk in this context is for situations when you're limited to the characters on the keyboard. You can write $4\cdot5$ or $4\times5$; there's no need for $4*5$. $\qquad$

comment Properties of the solution of a linear system with random equations
Are the $x_i$ independent of each other, and likewise the $y_i$, and are $x_i$ independent of $y_i$? You're omitting information. $\qquad$

comment Properties of the solution of a linear system with random equations
Are you asking about properties of least-squares estimates of $\alpha$ and $\beta$, rather than about $\alpha$ and $\beta$ themselves? $\qquad$

comment Why do we like sticking random variables into their own distributions?
It is reasonable to cal $f(s)\,ds$ a distribution. The function $s\mapsto f(s)$ is the density function of that distribution with respect to the measure $ds$. $\qquad$

comment Is there a way to do that integration?
Please observe proper MathJax coding as in my edits to this answer. Writing a\cos b or a\cos(b) results in proper spacing, thus: $a\cos b,\quad a\cos(b)$. $\qquad$
