Quick question about 2U Half-Yearly! (1 Viewer)

[adelaidecruz]

Hey guys so I've been doing a lot of half yearly past papers, and i just wanna ask, with questions regarding Maxima & minima problems, are the formulas given? (Surface area/area/vol/etc) or are we supposed to know it all by heart? Seems stupid idk but for me ive never really bothered to memorise all the formulas.. kind of time consuming to do too cos theres now way to know if youre getting a prism/cylinddr/etc..

Thanks!!

90% chance you have to know the formulae yourself, it's easy to remember once you practice enough.

They MIGHT give you the formula but most likely not.
