Hi, I'm thinking of majoring in actuarial (190/200 for combined ext 1 and 2 math) but I did not choose math1151 (higher math1A) this semester. Would I be able to choose actl1001 for semester 2? If yes, would I find it insanely hard considering I only would have done econ1203 (equivalent to...

Hey, I seriously considering on taking the commerce/ law degree at UNSW or USyd. What kind of jobs can I get and how 'good' are my job prospects if I'm thinking of going into finance (e.g. investment banking) with this double degree? Thanks <input id="gwProxy" type="hidden"><!--Session...

I'm considering on studying law and next year and was wondering what HSC subjects give an indication of how well you'll do in law?

four points P, Q, R, S lie on the rectangular hyperbola xy= c^2. let their parameters be p, q, r and s respectively. i.e. P is (cp, c/p) etc If P, Q, R, S lie on a circle of centre the origin, prove that pqrs=1 thanks

1.If Re(z^2 + z) is a constant, find the locus of z 2.If Re (z) is a constant find the locus of z^2 + z 3.p^2= p +1 find p^(-5) as linear polynomial in terms of p thanks

Hi, I am having trouble doing these two questions: Integrate: 1. (1 + cos 2x)/ (sin 2x)^2 answer given: -0.5(cosec 2x + cot 2x) + c 2. (sin 2x)^2/ (1 + cos 2x) answer given: x - 0.5sin2x + c thank you very much

From 2U fitzpatrick 11(e), Q 8 and 9 8. A man is receive six payments of $500 each, the first payment in a year's time and subsequent payments at two-yearly intevals. He invests each payment at 9% per annum. How much will he immediately have after the last payment is made? 9. What sum of...

Hey, would it be extremely beneficial if one did all or most ofthe 3U cambridge extension questions? Because, they are insanely hard and I don't know whether I should just skip them and do exercises up to only the 'development' section?

Can someone help me to this question :) Let triangle ABC be 90 degrees at C, so a^2 + b^c= c^2, find the ratio of c:a if: b is the geometric mean of a and c. Thanks

Given the moduli of z1= (2) - (3^0.5)(a) + ai and z2= (3^0.5)(b) - 1 + ((3^0.5) - b) i are equal, the argument of z2/ z1 is pi/2. Find the value of the real numbers a and b. Thanks

1. if z= cos a + isina express : i) 2z/ 1 + z^2 ii) 1- z^2/ 1 + z^2 in x + yi form where a and y are real functions of a thanks

If z= cos a + isin a, prove: 1/(z+1) = (1/2)(1 - itan a/2 ) thanks

I'm finding this question quite hard: Ch. 26b), Q10, fitzpatrick Given f(x)= sin (2x-3) for all x, write down the range of f. Show that a restriction of f, namely F, defined on [1,2], has an inverse F(-1). Find the rule of F(-1), stating its domain and range. Thanks

Show that: tan-1(4) - tan-1(3/5)= pi/4, thanks

Hey What are your thoughts on doing this 4-4 combo? With ext 2 maths and ext 2 english for HSC. I know it would be insanely hard, but is it worth the effort? How many people here are thinking of, or are currently doing ext 2 maths and ext 2 english? Thanks

a circular disc 8cm in diameter touches a flat surface at the point P. If the disc rolls 35cm how high is the point P above the flat surface? Thanks,

Hey, I'm having trouble with the following: Find the value of f '(a) in each case where it exists. f(x) = x, x>3 a=3 and a= -3 3, -3 <= x <= 3 x + 1, x < -3 My answer is: f '(3) cannot be found...

I'm doing philosophy distinction course next year and was wondering about the difficulty and workload about the course or even distinction courses in general. Do people make notes or is about memorising the given material?
