yes old M6
but this is still a bit of an extension


Shame, the books are all £50 on Waterstones
Intrinsic co-ordinates right?

correct !!

check for some copies in your school
or EDEXCEL M4 1995 editions (orange covers)

Found some intrinsic coordinates and radius of curvature in the old P4 textbook, page 56. No mechanics unfortunately but it'll have to do :lol:

MIT lecture notes online too: http://ocw.mit.edu/courses/aeronautics-and-astronautics/16-07-dynamics-fall-2009/lecture-notes/MIT16_07F09_Lec06.pdf
Any chance you have any A-Level pure questions like these for similar threads?

All the prerequisite reading is making me feel like I know nothing about maths (and truly I don't) :redface:

I have everything
hope they do not hurt ...

Edit: dudes you should spoiler such a big hint! But now that you've spoilered it anyway, here you go: http://www.ucl.ac.uk/~ucahad0/1302week2_intrinsic_summary.pdf

It's come to the point where I'm using your resources exclusively for everything A-level (and now beyond) maths :colondollar:

Thanks for all the fun and pain :u:

excellent stuff.
I can see a few questions stolen from there (adapted of course)

I really need to learn M6.

I used to think I was good at mechanics... let me know when you do some M5 questions for us plebs

Anyone brave ?
I think this is as hard as it gets

OK, I've ended up in a horrible mess of algebra which I don't have time to check properly so feel free to put up your solution - I'd like to see where/if I've gone astray. (And Binet's equation didn't help, nor did angular momentum - fat lot of good those hints were)

I hope that @A Slice of Pi also puts up his solution as he got the same answer as I

Oh my god, no wonder I went astray. The first line of my working after writing down the equations of motion is ψ=dydx=−sinh⁡x\psi = \frac{dy}{dx} = -\sinh x. It's time to shut up the maths books for good.
