comment How do I simplify this derivative?
It's a bit weird that the one who answered first got nothing, and I don't think a straight forward question like this needs three answers that none of them add anything new.

comment Evaluating $\int_A y^2 dA$
I think I get it now, but I have to double check the equation O had in the course book and make sure I can do it the same way. (congratulation for being a 1k user and thank you for your answer =)

comment Evaluating $\int_A y^2 dA$
@Fantini: Currently I am studying MS in Comutper Science and we didn't have to take such a course or at least I don't recall having taken it.

comment Evaluating $\int_A y^2 dA$
@mike: I still don't get it, I don't know how to evaluate such integrals. An example would be nice.

comment Evaluating $\int_A y^2 dA$
@Batman: Thanks, then do we integrate with respect to $x$ or $y$? And what's the role of $A$ beneath the integral sign?

comment Evaluating $\int_A y^2 dA$
@Batman: This is a problem in the book titled "mechanics of materials", I think no one on this site is interested in the concept. Just want to know more about the integral itself.

comment Consistency of the system $AX=b$
Could you state the reasons as to why when $\text{null} (A)$ it has one unique answer and infinitely many otherwise?

Thank you for your answer. I edited the question to clarify what I mean by $\mathbb R(A)$.

comment Why is smallest singular value of a singular matrix zero?
You're right @StephenMontgomery-Smith, I translated the statement into English and made that mistake. It was "singular" matrix.

comment How to show $((k+1)!)^2 2^k \leq (2(k+1))!$
@StevenStadnicki: Right, but your comment is a thorough answer as it stands. You could post it as an answer and ... Ta-Da! The problem is solved!

comment How to show $((k+1)!)^2 2^k \leq (2(k+1))!$
@StevenStadnicki: Why would you post a complete answer as a comment which left us with nothing?

comment Factorial of $(7/2)!$
For half-integer values, there's this Wikipedia article which explains it.
