    Got M1 this afternoon
    Killed my C 1 and 2 in January but I don't think i'll do as well in this, I keep on making stupid errors like forgetting g and subbing in the wrong values.

    The only preparation I'm doing this morning is making sure I have the right music in my head http://www.youtube.com/watch?v=c5QfXjsoNe4

    Make sure you turn off the radio on the way to your exam, or wear earphones. I had some awesome music in my head on my way to my C1 exam in January... and then Bruno Mars came on the radio :rolleyes:

    Could you tell me how you got 1/3 ms^-2 for the acceleration? :confused: really stumped. Thanks

    Also in vectors when something is north-east, south-east, north-west, south-west, to another object how do you go about those questions? I can do the ones which are due south or north
    Was about to reply to you in previous thread, but got closed ....

    u=1.5 s=6 t=3 ... a=?

    s=ut + 1/2 at2
    a=1/3

    NE... i=j
    NW .... -i=j
    SE... -i=j
    SW... i=j

    Hey thanks for that. So if we have two ships. Q is NE of R, so will the i vector of Q be equal to the j vector of R?

    Actually I got it, it's the resultant of the two ships. and then u equate the two

    EVERYTHING!!!!!!!!

    Maybe I can pass M1 today
    I dunno.
    I can solve most of the past paper qs but it also depends on whether or not I lose it in the exam hall

    C4 is an absolute nightmare
    I cant solve anything!

    So for NW, I know that -i = j but putting it in application, is it used in circumstances such as ships? For example, P is at the position vector p and Q is at the position vector q. Find the time when Q is north west of P.
    Do we find vector P-->Q and then equate -i = j?

    S_n = a + (a+d) + . . . + (a +(n-1)d)

S_n = (a +(n-1)d) + . . . + (a+d) + a

\mathrm{ Adding \ each \ term \ to \ the \ other:}

\Rightarrow 2S_n = n(2a +(n-1)d)

\Rightarrow S_n = \frac{n}{2}(2a +(n-1)d)

    yeh exactly that find PQ---> first, then equate it to -i=j and same if it was NE/SW/SE but i=j/ -i=-j/ i=-j respectively

    Anyone have notes for S1? Particularly those questions which we have to answer by text (comparing two things etc) Also any M2 notes are greatly appreciated!

    Quick question for M1 guys. When you are doing a calculation and substituting in previous values like using tension you worked out earlier to find out acceleration or vice versa; do you use the 3.s.f rounded figure or do you store the exact decimal in your calculator and then use that ?
