thank you

bruh maths teachers acting up fr why couldn't they just write '𝒾' lol

I swear ive done something with mod=1 before, but cant remember... Any clues on how to solve? thx!

Anyone been to/currently attending/heard of a tutoring place in Epping called 'Gifted Cluster for Advanced Maths' run by Stella? How did/do you find it?

i and ii are fine, but iii clearly is not. I calculated the midpoint of QR to be (5/4, 1). I compared that with the point (t, t^2) in being in the same linear equation and tried to find a formula, but tragically didnt work :,( Any ideas? Thanks :)

just going thru 3u revision across entire syllabus starting from FWWF lol probably the last opportunity i have to do that as well

very true [highkey embarrassing that i forgot the y=x rule omg] thank you

Q5b of the above hsc paper: - The graphs of y=f(x) [ for x>=0] and y=invf(x) [which I calculated to be ]meet at exactly one point P. Let α be the x-coordinate of P. Explain why α is a root of the equation x^3 +x -1 = 0. I let both function formulae equal each other and squared them and...

I made notes on solubility rules and memorised all but the 'mostly soluble' compounds. Any tips on the best way to memorise these? Mnemonics are good, but are there ones which cover all the ones here? [i.e. I learnt also that HydroxideCarbonatePhosphates are mostly Insoluble - a rule not...

Probably more specificity is needed, but generally use RICE (or ICE) tables first when you are info dumped - but make sure that all values are in the same units (that's when you use c1v1, m/MM formulae above to achieve that). Mainly you use ICE when in two cases: 1. Concentration of one initial...

with sketching the curve [how tf are you supposed to do latex bruh], why are there suddenly values of y>4 and y<=0 but no values 0<y<4? How to explain when writing range for function? Thanks in advance :)

a) Sketch a graph of the circle (x-3)^2 + y^2 = 1. [straightforward] b) The region inside the circle is rotated about the y-axis. Show that the volume of the solid formed is given by (x-3)^2 + y^2 = 1 and evaluate the integral. [I'm not sure what it means by ' Show that the volume of the solid...

Explain the relationship between the structure and behaviour of chromosomes during meiosis and the inheritance of genes - How would you write a 4-mark response to this question? I don't fully understand specifically what it means by the structures and behaviours of chromosomes... (This question...

no, I would just write (using AM/GM inequality) next to that final line of working that should be fine!

Worth 3 marks - am unsure in where to start - Please help (thanks!)

(sorry for the potato webcam quality) Q) Solve the allocated depressed cubic using the method of Cardano Could someone please explain in simple terms how to solve using Cardano's Method (I researched online but this could be more helpful)
