Hi, In maths exams primarily, I am prone to stupid mistakes. All the questions I make these silly mistakes on I can more than easily do! (which is why they're silly mistakes) How do I remove any of these silly errors? Thanks

Hi, I have to prove that the ends of a focal chord intersect at right angles on the directrix, though to prove these I need to use the fact that if PQ is a focal chord then, pq=-1. Can I use this in the proof? Or would I have to prove that to? Could I use the knowledge of the equation of...

Hi, Is there any particular topics whose questions are asked more in finals for year 11 then other topics? I've noticed that they ask more financial and statistics questions than algebra (not area), is this just something I've seen in a couple of papers or does it resonate throughout most...

Hi, In MX1 exams are we allowed to use the auxiliary method? Because it doesn't mention it in the syllabus? Are we allowed to memories and use the equation for a chord PQ, in parametric form, because it also doesn't mention that in the syllabus? I'm sure there is more of these, but I'm not...

Hi, I'm trying to find really hard preliminary MX1 exams (solely preliminary no induction, or differentiation of trigonometric functions), though they all seem to be on the same level (the ones I found in the resource section of this forum). Is there any particularly difficult exams that I...

Hi, How do you solve the following types of absolute value inequalities: 1. | f(x) | > | g(x) | (whether it's >, < >=, <= doesn't matter, and where f(x) and g(x) are both functions of x, not constants) 2. 1/(| f(x) |) > 1/(| g(x) |) (same deal as above ^) I know how to solve absolute...

Hi, We've started parametrics and there is a nice formula for finding the equation of a tangent at a point (xx_0 = 2a(y+y_1)) on a parabola. Are we allowed to just use this equation in a question? Or would we have to prove it? My teacher says if we wanted to use it in a question asking to...

Hi, I'm trying to see how well I need to go in my respective subjects to achieve a certain ATAR, as well as what subjects if I improved in would "boost" my ATAR more so than others. What ATAR calculator would you guys recommend? I like the look of the talent 100 calculator...

Hi, I've heard that equal is used for numbers, and congruence is to relate to "equal" shapes (same side lengths, same area etc.) in geometry but with a different location in space. But I don't understand why we use congruences in algebra such as: 3x^2 + 9x - 2 (congruent to) A(x-2) +...

Hi, What MX1 textbook has really hard questions that prepare you well for the HSC exam? I have Maths in Focus and I believe it to be a very easy textbook (that's my experience). Any recommendations of a better textbook for questions? Thanks

Hi, For exams do you guys have a favourite pen that helps you to write for longer and is more legible? I currently use a Papermate InkJoy 100 1.0M, though I'm thinking of trying some others out. Any suggestions? Thanks

Hi, I've seen and heard a lot about how the sum of all positive integers to infinity is -1/12 (This numberphile video was where I originally found it: https://youtu.be/w-I6XTVZXww). Is this true? I heard that somehow the Riemann Zeta function confirms it and they gave a proof with the Zeta...

Hi, I've had comments from numerous teachers saying that I need to write neater and faster. During exams my hands usually start to cramp up relatively quickly and this greatly affects the neatness of my writing. I heard about the old battery on the end of the pen trick, does it actually work...

Hi, If you guys could redo the HSC year and exams, what would you do differently? Thanks

Hi, In the syllabus it states "The formula for the distance between two points should be derived, as should the formula for the perpendicular distance of a point (x1, y1) from a line ax + by + c = 0.". In a few other sections it also talks about deriving the formula. Does this mean we...

Hi, I'm currently in year 11 and love math! I'm wanting to go ahead and do some HSC MX1 topics. What topics would you recommend that would get me ahead? Should I do the easy topics or the hard ones, that way I crack the tough nuts before I have to? Anything else I should know about going...

Hi, I'm currently in year 11 and love maths! I'm wanting to go ahead and do some extension 2 topics (I've already done complex numbers), that way when I get to it and it counts I should go well. What topics would you recommend (I'm not afraid to take on anything to hard) that would get me...

Hi, For chemistry (and in general science) notes how should they be written and formatted? Should you specifically address each dot point with what the dot point is above it? Or should you put it in more of a flowing manner, that goes from one idea to the next with reference to the dot...

Hi, Does anyone know of any resources for circle geometry questions? Thanks

Hi, I'm doing circle geometry questions at the moment (trying is probably a better word) and for a lot of them I struggle to see how to do solve the problems. Circle geometry just seems to be so much harder than the other topics, with the others I feel like you just go through a method and...
