    Semester One Results/Predictions

    Yes, your term WAM qualifies you to get PC according to the unsw concession algorithm. You should just attend MATH1231 classes, if you are really worried you should go to the math student centre in person or talk to the lecturer in charge of MATH1231.

    Semester One Results/Predictions

    I'm pretty sure PC is awarded according to an algorithm that depends on your overall WAM / term WAM. The UNSW concession algorithm comprise the following rules: 1. An undergraduate student is entitled to the award of Conceded Pass on a mark returned by the course authority between 46 and 49...

    general UNSW chit-chat

    Anyone know how long the NTEU results ban will last for? I've only received my provisional grade but not the mark for one of my math courses. The rest of math/stats results should be released by tomorrow.

    Equation of Tangent to Parabola

    (1) solve simulateneously for (x,y) to find the point of contact. i.e. rearrange x - 2y -2 = 0 in terms of y and subsubstite into x^2 = 16y. This will be a quadratic equation and hence you can find the point of contact which turns out to be (4,1). (2) Check the gradient of the curve y = 1/16...

    actuarial exemptions

    Having the technical knowledge is mandatory to pass the part I exams but having a deep understanding the acct/eco theory will definitely help a lot. Yes, it's possible to do a masters in actuarial studies in one year but it requires you to have full part I background. Check the unsw actuarial...

    math1151 for actl1001

    If your marks are good in econ1203, the school might approve you to enrol in actl1001 without math1151. The assumed math knowledge in actl would be the following topics which most of them you've covered in MXI/II anyway. 1) Geometric Series 2) Exponential and Logarithmic Functions 3)...

    UNSW Subject Reviews.

    Here's some review i've missed out on giving last year. My memory is a bit hazy because its been quite some time. MATH1151 Ease: 9/10 - Pretty much a breeze if you've done 4u math. Lecturer: 9/10 - J. du / T. Tran. Both excellent lecturers. Interest: 7/10 - Pretty much just goes through...

    Induction Question

    Well if (\frac{ab^k + ba^k}{4})\leq (\frac{a^{k+1}+b^{k+1}}{4}) then (\frac{a+b}{2})^{k+1}\leq (\frac{a^{k+1}+b^{k+1}}{4})+(\frac{a^{k+1}+b^{k+1}}{4})\\ =(\frac{a^{k+1}+b^{k+1}}{2})

    Integration

    let\; u = \sqrt{x-1} \\ u^2 = x-1 \\x = 1 + u^2 \\ 2udu = dx \\ \int\frac{1}{x\sqrt{x-1}}dx \\=2\int \frac{1}{u^2+1}du \\= 2\tan^{-1}u + c \\= 2\tan^{-1}\sqrt{x-1} + c

    Induction Question

    From where you left off, we want to prove this: (\frac{a+b}{2})^{k+1}\leq (\frac{a^{k+1}+b^{k+1}}{4})+(\frac{ab^k + ba^k}{4}) \leq (\frac{a^{k+1}+b^{k+1}}{2}) The above would be true if and only if: (\frac{ab^k + ba^k}{4})\leq (\frac{a^{k+1}+b^{k+1}}{4}) \\ \Leftrightarrow ab^k + ba^k \leq...

    Help! induction question

    For n = 1 LHS = 1^3 = 1^2 = RHS Thus, the result is true for n = 1. Assume the result is true for n = k, i.e. 1^3 + ....... + k^3 = (1 + 2 + .... + k)^2 (I) We need to show the result is true for n = k+1, i.e. 1^3 + ....... + k^3 + (k+1)^3 =...

    Probability Question

    Using the inclusion - exclusion principle, we have: P(A or B) = P (A) + P (B) - P(A and B) Substituting, 15/16 = 6/16 + P(B) - 2/16 So P(B) = 11/16. Alternatively, you can draw a Ven-diagram with two circles sharing an intersection. Labeling the first circle A and other circle B. You can assume...

    actuarial exemptions

    Not sure if its relevant, but has anyone heard about the recent changes to how AIAA (associate) is awarded and the term "actuary" is used? I just stumbled upon the institute of actuaries of australia website and found some changes. Apparently to become an associate (AIAA) now you not only need...
