if your good at selective tests style exams do the HAST, i think there are also other good schools who offer positions based on HAST. If not i would still suggest putting one of the HAST test schools down in case you get a good percentile, because they dont care about your preference placements.

once u learn math properly u never forget.

This is the 2021 integration marathon thread, as i have noticed users submitting integrals on previous year's threads. I will start off: 1/(x+x^6) sorry for bad formatting

He didnt integrate, he realized it was a semi circle and after a sub and then he used the area of a circle formula to find the area beneath the curve. This is just an instance where it is easier to use properties of the curve rather than integrating it.

ye sure, but for clarity they still have concentrations.

quick proof: c = n/v= n x 1/v = mass/MM X 1/v = m/v X 1/MM = 1/MM X P. where P is density which is constant for solids and liquids and 1/MM is a constant as it is molar mass which is fixed. Thus concentration is constant. sorry for poor formatting.

well actually they do have a concentration, its just that having a constant concentration in the eq constant provides no additional information so they just disregard that info.

ye when i watched the mit integration bee i felt it was an easy expansion + reverse pro rule, iirc neither of the contestants got it right.

no i mean a hsc mark of 94 will get you a 99.95 provided that all your other subjects give you 99.95 atar equivalent.

Be careful of where you allocate your time, because even though a mid to high e4 in ext 2 is desirable the effect of scaling becomes less and less iirc 94 in ext 2 scales to a 99.95. Therefore your time is better spent on weaker or worse scaling subjects.

series and sequences is easy enough to finish in a couple hours, so i say just learn series and sequences first.

I didnt pay attention in science from yr 7-10 but just self studied mod 1 for phys and chem in the summer hols and it was enough to do well.

both ive seen the Un realtionships but i can only find first order ones. I would also like more challenging recursion material if possible.

would the emerging field of 'big data' be placed under the latter 2 mentioned in the least employable degrees. I've heard it is one of the biggest and most employable fields.

enrichment 2E, q22

nah, not 2nd order recursive ones.

anyone know where to find good q's for 2nd order recursion proofs, Cambridge only has a handful of basic ones, not sure where to find anymore. Also i dont want to look through past papers as i would like to keep them for trial period. thanks.

i think it is valid to sub in z=1 unless it is stated z=/1 in the q and or the fraction in (b) is given.
