So a = 0 or a > 0. If a=0 then the proof shows the right triangle must be the representation of a non-primitive Pythagorean triple. When a >0 then Z(n) is greater than X(n) + Y(n). I did want to thank you for bringing up so many issues. This has made me examine the theorem in a different way. It may be possible to construct a different proof. So thank you for that.
You're very welcome. Glad I was able to help clarify the issues.

If there is, then it certainly would have been found by now....

Nor does anyone else on this forum. Why don't you make yourself useful and find some other better mathematicians to look and see if they can find an error in the proof.

I already showed you the error in your proof. If there were a Fermat triple $x^{10} + y^{10} = z^{10}$ then there would be a Pythagorean triple $(x^5)^2 + (y^5)^2 = (z^5)^2$ and your $\alpha$ would be zero. Then the rest of your proof would fail.

You seemed to acknowledge this error earlier, and now you're back to ... what, exactly? You haven't got a new proof and you already acknowledged the failure of your earlier proof.

You understand that the burden of proof is on you, don't you? If a member (or anyone else in the world) wants to look at your proof and finds an objection then it is upon you to defend it. It doesn't matter if someone agrees with you or not. It doesn't matter if you don't like the person or the question. Denis does not need to go over your proof to find a proof that says your ideas are wrong. You just have to accept that this is going to happen. Sorry but that's the real world of academia.

In addition there have been a number of Mathematicians that have worked to show that there is no simple proof of FLT using algebra and that should translate into no proof by trigonometry as well. This is why you are getting so much resistance.

Someone in this thread once asked you to disprove $\displaystyle a^3 + b^3 = c^3$. You haven't done so. If you could give the full argument about why this equation fails it will generate you some more support for your ideas.

I thought he was addressing Denis. But then he said, "Nor does anyone else on this forum.' I'd been under the impression earlier that I've made my point.

Not only that ... I had a rare experience, that of getting through to an, let us say, alternative thinker. I rarely engage with FLT threads because of the likely futility of the enterprise. I was gratified that I was able to make a mathematical point and that the OP agreed that it refuted his proof.

The OP's latest makes me doubt all that. Perhaps that didn't happen earlier at all. Or perhaps the OP got the point earlier but now isn't so sure.

I await clarification from the michaelcweir.

I rarely engage with FLT posts because of the likely futility of the enterprise. So I was gratified that we had a mathematical meeting of the minds and that I was able to communicate some math to someone who understood that it showed that they don't have a proof.

Yes. If you get an amateur FLT-prover to admit his proof is bad, that is an accomplishment on par of proving the FLT itself. But I doubt you did it, if I saw his latest post.
