note that either f(x) or f-(x) cannot be a function if the two intersect at a point that is not on the line y=x i.e. if both function and inverse are functions the only points of intersection lie on y=x

Re: why the mass of the planet plays no role in determining a satellite's orbital spe theres no 2 just (GM/r)^1/2

re: HSC Physics Marathon Archive I would say A more than B although A is not perfect.... non of these answers are right. The real graph should look very similar to B, but it must extend below the t axis for at least a infinitesimal period of time. How would you get a moving stone to stop...

what are the main points needed for an answer to a slingshot question? yeh it depends on the question, but usually im thinking some of these - 1. diagram with vector addition shown 2. Conservation of Kinetic Energy + how this applies 3. Conservation of momentum + how this applies 4...

lol same was literally the most cliched place to have a sci fi creative. and the photoshopped brain was ridiculous some high tech microsoft word shit

srs? most questions were pretty generic

that wasnt all i said - i worked out the roots and wrote the formula for product of roots but i used the leading coefficient as one instead of the sum of binomial coefficients

hsc 2016?

hey carrot how many marks would i lose for saying the product of the coses in the second last question was (-1)^n

i think in the end the mu the used does not correspond to any coefficient of friction they made their own laws. meh fair enough its a maths test

good boy

dude. how is mu a variable? you of all people should know ;)

no its not a variable. but i was thrown off by the equation we had to prove because in physics the static coefficient time the normal represents the maximum frictional force that can be provided, so the v they used in the first part was clearly the 'breaking point' past which the car would slide...

EXACTLY they fucked up the physics real hard i actually wrote an essay in the exam telling them how badly they fucked up

and whats wrong with 11a?

no, whats wrong with 2?

yeah same i checked the questions carrot definitely copied it wrong uhhhhhh saved

the complex number graph one? i think carrot copied the question wrong (z^2-z*, not z^2-z*^2)

love bruh

yep
