Re: Easy puzzle challenge

A minor alternative that can make the calculus a little easier:

Question: it was pretty easy to guess how to hide the solution, but how do you get alternative text other "Hidden Text"?

Re: Easy puzzle challenge

Hi eigenguy,

...how do you get alternative text other "Hidden Text"?

After "[hide", type "=", followed immediately by the text of your choice and the closing bracket ']'.

Here...I'll try it with "minor alternative" in the hide box:

Just click on 'Quote' in the bottom right-hand corner of my post to see what I did.

Re: Easy puzzle challenge


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Thanks!

It's been a while since been in a forum. It's embarrassing that I'd forgotten about the quote trick!

Hi;

Did you see my completely original answer. I trust that JFF would like it.

Re: Easy puzzle challenge

Can I remind everyone that the title of this thread is Easy puzzle challenge. Therefore if your solution is messy and complicated, you’re on the wrong tack.

Yet, that's harder than what's shown in #31

Re: Easy puzzle challenge

I guess DeMoivre's and Vieta's is a bit of an overkill but maths is all about solving problems in different ways.

Yeah, proofs of even simple results can sometimes be a bit messy. hmm

Still true today as it was then. Anyway, how about another problem.

Re: Easy puzzle challenge

You'd better add "monic" to your description of f, or else it can't be proved, since for any a, af(x) is another polynomial with the same roots.
