I want to apply for a double degree in Advanced Mathematics and Civil Engineering. How do I say that in my UAC application?

Like for an ellipse: xx1/a^2 + yy1/b^2 = 1??? Or do we have to work it out? I can do both but quoting it is a MASSIVE time saver

I don't get the difference between the dotpoint in students learn to and the dotpoint in "students"? What should I focus on in each, and how would the questions on them be different?

Are dx and delta-x interchangable? If, say, I wrote delta-x in normal integration or I used dx as the thickness of a cylinder in volumes, would that be regarded as incorrect?

I can't seem to get this one: Show that a^2 + b^2 + c^2 >= ab + bc + ca and hence show that: b) a^2 + b^2 + c^2 >= 3(a^2 * b^2 * c^2)^{1/3} I got the first part, its just (b) that I dont know how to work with :/ any hints greatly appreciated.

Is it possible for me to do a double degree in Civil Engineering and Maths? If so, how long would it take? And how much extra work would it be compared to taking a single degree?

For some reason my answer is completely off the asnwers in the back of my book. My method: sin3x = sin2x sin3x - sin2x = 0 but sin(A+B) - sin(A-B) = 2sinBcosA A + B = 3x; -A + B = -2x 2A = 5x ; A = 5x/2 2B = x; B = x/2 Therefore sin(3x) - sin(2x) = 2sin(x/2)cos(5x/2) = 0 i.e...

Are these three general solutions the same answer? 1) 2n*pi + pi/3 2) 2n*pi +/- pi/3 3) 2n*pi - pi/3 I know 2 contains both 1 and 3, but does 1 contain 3 and so on?

I have no idea what I'm doing wrong with this question: P( p, 1/p) and Q (q, 1/q) are two varibale points on the rectangular hyperbola xy = 1. a) If M is the midpoint of the chord PQ and OM is perpendicular to PQ, express q in terms of p I found: M = ((p+q)/2, (p+q)/2pq) m(OM) = 1/pq...

The question is (Question 9 from Fitz. 4 Unit 32(c)): "P is a variable point on the ellipse with equation: \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 and S and S' are the focii. Show that PS and PS' are equally inclined to the tangent at P." I have no idea what I'm trying to prove. What does it...

Conics is by far the topic I've had the most trouble with in 4 unit (should've probably expected it since I had similar trouble with the 3 unit parametric stuff). Does anyone have any general tips for the ellipse and hyperbola problems that would help?

School Ranking: ~220 Advanced English: 2/16 Chemistry: 3/14 Physics: 3/11 3U Maths: 1/1 - ~90% in Half Yearlies (my teacher mainly put harder HSC questions in this one) 4U Maths: 1/1 - ~80% in Half Yearlies (only complex, graphs and adv. 3 unit HSC questions, so not a good estimate and...

The first part of the question is: "A body, initially at room temperature 20 degrees celcius, is heated....." They gave me Newton's Law of Cooling, which is: dT/dt = -k(T-M) where M = the surrounding temperature, T = the temperature of the body and k is just a constant. I...

Just checking if I'm far behind everyone else, since we started the whole subject an entire term behind. The topics we've done so far are: 1-Graphs 2- Complex Numbers 3- Integration 4 - Polynomials Starting conics next week, and we've got mechanics, volumes and Adv. 3 Unit left. So...

In one of my textbooks, the final rule for naming if there is more than one possible name is: "The correct name is the one in which the lowest locant is assigned to the functional group cited first as a prefix" i.e. it goes by alphabetical order In another, the final rule is: "The...

At the moment, I have 11 units --> Advanced English, Chemistry, Physics, Visual Art and Extension 1 Maths (+AdvancedMaths) Due to a change in principles in my school, I was finally offered 4 unit maths last week (a bit late I know). However, I have to drop a subject to be able to put in 4 unit...

For the question showing a teacher holding a balloon and blowing it what theory was it representing? :S I put in the Big Bang Theory?
