STEP Prep Thread 2015

I might be being a bit dense, but what does it mean to "solve the equation" but not solve for x?

Can you give me an example?

The STEP questions that I've done tend to have fairly nice solutions, although I probably haven't done enough to say that this is always the case. However I'm anticipating that the solutions to this equation will be messy.

I had a go at solving it. I've simplified it as much as I can, but I'm finding it hard to rearrange into a form that I can actually solve. Is there a trick to this?

Sorry, I had a brain-fart just then. I take back what I said. How embarrassing. I agree it means to solve the equation for x.

Apologies >.<

I believe there are multiple solutions for x. If there is a trick to solving this, I don't have it.

haha, it happens to everyone.




I'm curious now as to how you would solve this. It might be worth posting it on the main forum to see if anyone else can think of a method. Where did you find it?

Is this question STEP quality?

Solve the equation, reducing $x$ to its simplest form.

$\dfrac{(3x^2-27)(8x^2)6}{4(9-3x)(x^2 +3x)} = \dfrac{\tan(x+4)}{\log(x+\frac{1}{4})}$

The LHS reduces to -2x if that helps.
I have no idea how to solve it other than using numerical methods/graphically though.

Dunno where to post this but if you get an offer then do you take for example, both AEA and step (do they pick the best or do you give them the best result?- because its not like an a level so its not a qualification so i dont know whether you have to put it down..) Let's say you get a cam offer then should you take all 3?
Thanks

Smartest people on TSR chill on this thread. Just thought I'd add that in.

I would not want to chill in Ukraine even if I got to chill with smart people.

lol i was supposed to write ikr but spell check changed it to Ukraine lol

Does anyone know of any step questions that only require C1 knowledge and maybe a bit of C2 (we've done factor/remainer theorem, logs and circles)? (or perhaps questions involving only m1/s1 knowledge) I feel like trying a step question

Thanks

Off the top of my head have a look at STEP I 2000 Q1,2 (Q2 needs knowledge of binomial expansions) and STEP I 2001 Q1.

STEP I 1994, Q5 (a good question, requiring only a little calculus, coordinate geometry, and thought).

STEP I 1999, Q1 and Q9 (the latter is a mechanics question). Q1 is very much a sort of maths challenge vibe.

Thank you, I will have a look at these



Thanks But how do I find the STEP papers from before 1998? It only goes back to 1998 on their website

You can get all of them here. Excellent website, has a load of MAT papers too (which only require C1 and C2, so it may be worth checking them out).
