Hi Bob

The equation for x I am getting does not have a solution.

EDIT: When the chords intersect outside the circle I get the answers x=3/5 and x=18/5.

Or, you could just say that, for any integer n, x^(2n)>0.

Also, I was confused by the question. It seems, by what you wanted, that it should have been "Is f>0 for every x in R?".

You're welcome, but I sure am hoping you are using that as a figure of speech only. smile

I cannot begin to imagine it! Thanks for keeping the forum clean!

You're welcome! smile

The problem is quite tricky!

The thing is that, fortunately, we do not get to see the ad hominem attacks, since most are moderated. What's left of their posts seems really funny, because they give themselves huge accomplishments.

Fixed the post a bit.

Hi guys,

Oh, sorry, I read it as 1/sqrt(...). That makes it different, sorry.

Yeah.

Hi Agnishom

Did you see post #24 here?

#1172 Re: Exercises » A nice integral » 2014-02-06 02:58:48

Hi Yusuke00

The first can also be solved using x^4+x^2+1=(x^2-x+1)(x^2+x+1) without complex numbers.

For the second one, I am getting
