Sorry do you have a source?

Source? Someone just told me they thought it was 5 years haha :/

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?

I have really horrible memory so I just avoid even trying to memorise stuff because I know I'll end up forgetting it under pressure :/. Out of curiosity, would this really get you a full mark for questions a tad harder than this in the HSC?

Gah I feel so stupid now for missing both of those points. Thanks a lot! Edit: I'm still getting the wrong second answer for some reason ((pi)/5 + 2n(pi)/5) :/

First thing to do is to seperate your working out into three sections: 1-Digit numbers, 2-Digit numbers and 3-Digit Numbers (remember that the number <600)

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...

Term 1 this year :mad2:

Content wise, we've just started mechanics and still have all of harder 3 unit left (I'm blaming this on being an entire term late, thanks). Work wise I've still got questions from pretty much most off the topics that I haven't done yet but will definitely be catching up on (mainly conics and...

Which part of chemical monitoring and management? I remember that module and production of materials being pretty much based on memorising. Also, to OP, like everyone else said, Year 11 Chem is harder than Year 12. (The lattice crap still gives me nightmares...*war flashbacks*). I recommend you...

Thanks for the replies. I tried subbing in random integers and it didn't seem to work out, but I just wanted to double check as, in the harder 3 unit part of 4 unit, i kept getting answers without the +/- in there before things like pi/3 or pi/10 (which were in the answers) unless I changed the...

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?

Oh my god! I found it like three times and all those times I completely forgot to keep the negative in I'm so stupid ugh. Thanks again! Also, I guess it would be +/- 1/q as opposed to 1/q?

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...

I've got another question I need a bit of quick help with though. The question is: 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...

Thanks, guys! I'll try it out now. Edit: Awesome got it! Thanks so much! And yep, I ended up using the angle-between-two-lines formula, ending up with: tan(/alpha) = -tan(/beta) The angle alpha is therefore the same size as beta, meaning that PS and PS' are equally inclined to the...

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?

6÷2(1+2) From what I see, that would be written as 6/2(1+2), not (6/2) * (1+2) as (1+2) is only connected to the 2 so it's = 6/2(1+2) = 3/(1+2) = 3/3 = 1????
