    I'm not great at relating integrals to series. Either with Maclauren or binomial or just other (normally infinite) series, anyon have any advice as I think they're quite common. Cheers

    I dont mind the mathmos knowing my name since a fair few of them do. but random people, no thanks.
    Oh ****, man. I thought you were the other guy. Your request is the better one btw, I got confused there.

    Removed it from my quote. You also probably want to remove this post too, once Insight has censored it
    The request you posted intiially was the better one, I am just a retard boy.

    Top tips for doing well on STEP: remember that the derivative of sin is cos, and the derivative of cos is -sin, not the other way round.
    Sine is fine cos is odd

    Nah I just derive it in the exam if I can't remember. Also e^x is quite a tricky one to remember, so I usually derive that too just to be on the safe side.

    I do usually remember it, I think I just wrote it down wrong. (And technically cos is even, sine is odd!)

    Acronym inside an acronym. I like it.

    I wonder if we can go deeper.

    I thought every remembers it at the sum of the even function cosh and the odd function sinh?

    Nah it's for diff stuff, sin goes to cos, cos goes to -sin, hence the odd

    Did you guys know that the first four letters of Stephen Siklos' name make up the word STEP?

    Coincidence? I think not.

    Edit: 1, 2, 3, 4. Yay!

    I actually didn't make a typo. I miscounted. I hope Camb isn't watching.

    STEP III 2015:
    Spoiler:
    Show
    I thought this was a weird paper, due to the three questions on proof that weren't on any normal A-level stuff at all (not complaining, because they were quite nice).

    2 - pretty straightforward
    5 - also pretty straightforward, except I couldn't get the if part at the start of (ii)
    6 - gave myself 2 marks for an attempt at half of (i)
    7 - nice question
    8 - would have been an easy full if I hadn't for some reason differentiated sin as -cos and vice versa. Instead it was an easy half.
    12 - (i) fairly easy, although a bit dodgy that you didn't seem to have to prove that Rn's p.g.f. was always G(x). Didn't make much progress in (ii), and looking at the mark scheme it looked horrendous
    13 - drew a little graph, gave up

    Overall 73, a solidish 1. Not bad, although it was a bit odd I wouldn't mind a paper like it this year.

    Wait a minute.

    1. STEP is made up of three letters.
    2. STEP is also made up of three papers - I, II, III.

    However, STEP is not made up of three letters, so by using proof by contradiction it has been proven that STEP is also not made up of three papers. STEP IV is being secretly hidden by Siklos confirmed. QED Illuminati controls STEP confirmed.

    Try to refute my logic, you mortal peasants.

    Pro-tip: You can't.

    Using the principles of strong induction (thank you zacin bas$d God)
    We can consider the initial case, where step has 3 letters.
    1-S
    2-T
    3-E
    4-P
    .......... Oh my gawd, step 4 confirmed
