Ok, thank you very much :)

Ok, thank you. I believe I understand it better. So only use congruent symbol in geometry (stating shapes are "equal" but not in position), for identities and for defining variables in terms of variables?

Ok, in this question (http://community.boredofstudies.org/showthread.php?s=&goto=lastpost&threadid=352722) InteGrand you used congruent for part b, let w congruent to r^2 - z^2. Why did you use congruent instead of equal to?

Ok, if I had y = 3x^2 + 9, should it be congruent or equal?

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) +...

How do you improve your handwriting?

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

Ok, thank you very much. That is very interesting about the definitions, I never thought of it that way. I will have a read of the blog post :)

What would be a lighter pen?

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

That was meant solely as an example. For any other level of mathematics and formulas and results should I memorise the proofs?

Ok, should I remember and memorise the proofs?

Is it likely they will ask a question about deriving a formula? Has it happened before?

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...

Ok, thanks :)

Ok, did you do any 2 unit?

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...
