Graphing Conic Sections
Hello,
I was wondering if anyone knows of any apps that can graph such things as ellipses, circles, and hyperbolas?
I certainly have a few apps in which you can enter a function and get a graph for it, but what about being able

Alteration of Digits in Integers Problem
How in the world does one go about solving this? Is it even possible? It must be if it is on a math test...(An Olympiad Test, mind you.)

Thank you Misz.Lopez for the encouraging answer and welcome to this forum. That's the exact attitude I was hoping to see in users when I first clicked onto this .

That is exactly what I wanted. A way to reduce and organize this seemingly complicated idea/requirement into something as clear and workable as an algebra formula. Due to your explanation of the logic I am now fully satisfied and convinced. Thanks for taking the time to solve this and explain it.

Uh oh. I wonder if there is a strict systematic method or concept that exists to solve this...Or if they just expect us to test out different theories until we find one without contradictions.
(an example of what I mean by 'concept' is 'cyclicity', which is necessary to solve problems like what is the units digit of 9 to the power of 56).

I think your answer 'any integer ending with zero' is probably indeed the only answer which doesn't have any counterexamples. You don't need to explain the logic of it...I'm so tired of this problem haha...Anyways, thank you for taking the time to help me with this.

Oh dear, yes. Sorry, this nasty little problem is making my brain fuzzy. And one that does actually work is 55 obviously.

105, but I just realized that 5 actually doesn't work because the number 25 contradicts it. (25 is not divisible by 2.)

Seems like your answer 'when the last digit is 5' always works, though.
I definitely understand that any integer with the last digit is 0 will work...But any logic as to the process of which you deduced it would be much appreciated.

Hello Melody, likewise.
Thanks for the answer to that and my palindrome problem; I found it on an interesting site full of all the types of strange math questions which I don't know the precise procedure for solving and therefore am usually frustrated by. I would like to post all such questions I find until my ability to organize the seemingly-only-do-able-through-brute-force-aka-trial-and-error problems into clear methodical procedures is such that I will no longer dread, but rather look forward to those problems my math books usually catch me off guard with. Well, there's a lot of 'em. Better get posting .
