STEP 1 2016 Q11 solution. This is one I did in the paper... Thought it was a very long one actually, perhaps there was a shortcut I missed (would appreciate people looking for one). Ended in a show that which is always comforting.

Agreed.


That's a relief:/

Q1. I feel like there was another part as it seems a bit small, but then again I only proved it for n=1 and said, do the same thing.
Q1 STEP I 2016.jpg I'll let you blow it up again. :tongue:


Note that p4(1) = 2^8 - 9(1)(3^3)=256-243=13
q4(1) = 2/2 = 1

So the two polynomials cannot be equal.

Much easier than wading through half a page of algebra!

I'm obviously not going to upload any solutions until you give the go-ahead, but could I perhaps do the solutions for STEP II questions 6, 13 and that one? :smile:


Believe it was question 7 or 8, but probably shouldn't mention what the topic is just in case

You're right, my apologies!


Ith cool, only 21 hours to go!

That probably could have saved me some time in the exam. It looks like I went a very long way around it. I was thinking, "surely there's an easier way to do this", but didn't think to do that.
can I do q5

Sure, sounds good. You can post it up at 9 a.m tomorrow morning.
Nice solutions guys, just wondering where I can find the paper? There were photos on here yesterday but can't find them now? thanks

I've posted the link to the pdf a few times on the main thread, you can go look 'em up there.

It's here (might be useful if it was added to the OP of this thread).
