    I think it will be harder than last year but not half as hard as 2011/2012! Thank
    god!
    I wonder what they'all base the Context and Applications questions on?!

    In context and application I'm expecting a financial maths question, an exponential function/logs question and some sort of calculus question, probably integration orientated.

    First 6 questions are fairly obvious.

    Ah I'd love a Financial Maths long question!

    That's all I've learned, and how to get the average value of a function too.. Is that it?

    @LCStudent2014

    Want (what you're looking for) = Given (given in question in written terms so you have to change it to maths terms) multiplied by Need (construct this from the two other parts) kind of hard to explain on this sorry!

    Amortisation Formula, De Moivres Theorem for all n is an element of N also.

    Isn't that in the log tables?

    The contrast between the 2013 and 2011/12 papers is ridiculous. It would be amazing if it was like last years, but I'm expecting pure filth tomorrow..

    How do you prove root 2 is irrational?

    Does anyone know if that formula for average value of a function is in the log tables? Also in the 2011 papers, in the question on integration, is that type of question still on the course where you have to make some type of substitution and change the limits etc? I haven't been able to find any reference to it in any of the maths books...
    Thanks guys!

    And complex numbers, and the root of a function and differentiation/integration.

    Common sense stuff that should come up would be simultaneous equations, -b formula stuff like that!Fingers crossed!
