    Re: BoS Maths Trials 2018

    Hey with Q16 d) i) we use the fact that I(1/b) = I(b) - 2*pi*ln(b), which leads to an obvious statement which makes the show question true. However, we are using the result from c) v) which is only reached assuming a > 1. In d) b > 0. So isnt that a logical fallacy? Note you have to use part i to do part ii, which furthers the illogical result.

    No. The case 0<b<1 can be transformed via a functional equation into the valid domain over where the result was proven to be true. Perhaps you should keep staring at the paper.
    If I am a conic section, then my e = ∞

    Just so we don't have this discussion in the future, my definition of the natural numbers includes 0.

    Re: BoS Maths Trials 2018

    Should also remark that a surprising number of people actually left questions unattempted in the MC. If you don't know the answer then guess it!
