    Third derivative method

    if 'properly qualified' means that they have to accept things like the 3rd deriv test, then theres probably no school where every math teacher is qualified...and u dont get to pick ur teacher once you're in a school, so dont enrol in any school? but just how many 'properly trained teachers'...

    Determinant Prob.

    properties of determinant that u need: det(AB) = det(A)det(B) det(A-1) = 1/det(A) det(cA) = cndet(A) for A in Rn hope uve seen those before =) so then det(A-x-1I) / det(A) = det((A-x-1I)A-1) = det(I - x-1A-1) = (-1)3det(A-1x-1 - I) = - det(A-1 - xI) / x3

    Challenging probability question

    (iii) P(r,s) = P(throw r heads before s tails) "throw r heads before s tails"... this is equivalent to: "in the first r+s-1 throws, he throws at least r heads", since: - if he doesnt, then he has thrown <= r-1 heads, and so he has thrown >= s tails, so not r heads before s tails - if he...

    How hard is Actuarial Studies

    to 2nd+ yr students: what is the min mark that u think we should require in ACTL1001 to be able to manage the actl subjects in the future? i know they set the benchmark at a credit, but for example, would someone who just gets exactly 65 be able to do reasonably well in later years?
