A list of testable proof (1 Viewer)

[get_back23]

The stuff that we normally use without proof

Would be a bitch if we lost marks on these, sometimes they ask for it don't they?

Any know any, please post them here

Heres a few that i know :

d(0.5v^2)/dx=acceleration
proof for t formula
proof for circle geometry theorems, like (angle at tangent = angle in the alternate segment)
nCr=nCn-r


Pretty sure theres more

if you just use them directly, u cant lose marks can u?

No u won't, unless specified to do so.

sums and difference formulas

sums and difference formulas

You don't need to know the proofs of those.

 

[Jashua_Long]

Well, even though you probably don't realise it, all of projectile motion is remember proofs (though it is all very easy to remember).

All of parametrics is basically proof.

That was asked in 2009. Probability of it being asked this year =0

was doing the 09 paper just before. got to that and was stumped. well, at least I know how to do it now.

Lol. Untill now I was stupid enough to derive that formula for every 3u test I had. I didn't know we could quote it.
(but then again, i like deriving things - only formula I have to remember is fkn newton's method)

edit: ohh and like 2 or 3 circle geo rules. (hate them)
