comment Algebraic word problem involving auxiliary variable
Josh, I was able to use this answer in finding my solution. My solution is somewhat different, but the visual was extremely helpful in setting everything up. Thank you very much for your help.

comment How to prove algebraic theorem of the solution set of the equation ax+b=c using field axioms
So, If I am understanding correctly: (b) the empty set would be written out like this : ax+b=c, where a=0 and b is NOT equal to c, we have, ax+b=0--> 0x+b=c given--> 0+b=c by theorem a(0)=0 --> 0-0+b=c-0 by additive inverse --> b=c-0 simplify --> b does NOT =0 does writing it out like this make sense?

comment Show lines segments parallel?
I would assume they intersect at a point, $p$. Then, I was thinking to use the parallel lines before dilation to show (by contradiction) that they can't intersect...

comment Show lines segments parallel?
Thank you. So, it wouldn't be correct to prove by showing they don't intersect?

comment Show lines segments parallel?
Someone asked me this question, so I'm not sure if I can assume that. I did show the first part of your statement though. If I can't assume your second statement, how can I prove it?

Thanks! Is there a way I can check this before I attempt to solve the entire solution?

comment Problem with solution for non homogeneous differential equation
@abel So I would need $y_p=Ax^2+Bx+C+Dxe^{2x}+Ee^{2x}$ ?

comment L'Hopital's Rule, Factorials, and Derivatives
@Squirtle So the factorial function as we know it (defined over ℕ) is not continuous over ℝ?

comment L'Hopital's Rule, Factorials, and Derivatives
@SherlockHolmes Thank you, I saw that question as I was searching. I read about the Gamma function, but I don't fully understand. I think it's because I don't fully understand how factorials and derivatives work (or don't work)

comment Understanding the change-of-coordinate matrix
You mean $[T]_\beta^\gamma$? What would be the interpretation of this?

comment Understanding the change-of-coordinate matrix
Okay, I think I see what you mean. Thank you. So would $[T]_\beta$ mean the representation of $T$ with respect to the basis $\beta$?

So $A$ would change the scalar elements?
