 Nov 2 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. Oct 30 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? Oct 5 comment Proofs involving triangles and rectangles Im having trouble getting started and thinking about it. Im not sure to go about proving it @AlexZorn Sep 23 comment Show lines segments parallel? Thanks for the help! Sep 23 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... Sep 23 comment Show lines segments parallel? Thank you. So, it wouldn't be correct to prove by showing they don't intersect? Sep 23 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? Mar 24 comment Problem with solution for non homogeneous differential equation Thanks! Is there a way I can check this before I attempt to solve the entire solution? Mar 24 comment Problem with solution for non homogeneous differential equation @abel So I would need $y_p=Ax^2+Bx+C+Dxe^{2x}+Ee^{2x}$ ? Oct 23 comment L'Hopital's Rule, Factorials, and Derivatives Very helpful, thank you! Oct 23 comment L'Hopital's Rule, Factorials, and Derivatives @Squirtle Thank you! Yes, that's exactly what confused me! Oct 23 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? Oct 23 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) Dec 18 comment Understanding the change-of-coordinate matrix Thank you for all your help! Dec 18 comment Understanding the change-of-coordinate matrix You mean $[T]_\beta^\gamma$? What would be the interpretation of this? Dec 18 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 $\beta$? Dec 18 comment Understanding the change-of-coordinate matrix So $A$ would change the scalar elements? Dec 17 comment Exponential distribution, am I doing this correctly? Thanks for your help! Dec 17 comment Exponential distribution, am I doing this correctly? Thank you for your help! Dec 17 comment Probability question..how to set up? Thank you, but would I need to calculate the binomial for 3 or more?
