Can anybody post a full solution of the Brachistochrone problem provided by Newton (with full explanations) ?

Or, any source about the same would be much helpful.

Thank you in advance !

Yes. But, I don't think I understand the solution of Newton provided in wikipedia.

The short answer to this is no. We can try to help you understand how to solve this problem, but you still have to do the work.

I don't think I understand the solution of Newton provided in wikipedia.

What are you having trouble understanding?

LOL The proof is already there. All I need is a good resource to understand it.

What are you having trouble understanding?
Pretty much everything. I think I understand the Fermat's principle method (till the DE). But, no solution of the DE is provided in wikipedia to conclude that it is indeed a cycloid.

Mind referring a source ?

The best way to understand it is to solve it yourself. Having a known solution as a guide is often helpful, yes.

Which Wikipedia article are you looking at?

I'm confused. If we typed out the proof - which would be the same one in Wikipedia - how would that help you better understand it?
