Quick question regarding the hsc markers (2 Viewers)

Am i allowed to use the FORBIDDEN FRENCH METHOD in doing maths in the HSC?

 

[SunnyScience]

care to elaborate?

 

[Shadowdude]

the what

 

[RealiseNothing]

Going to take a guess and say you are talking about L'Hópital's Rule?

 

[U MAD BRO]

it is a great rule, idk why we're not allowed to use it
can we use taylor series expansion for limits instead of L'Hópital's ?

Doubt it.

AWWWW, lol i dont't even know what it is, but they are forbidden techniques that only some people know for ext2 mostly, not sure...

but does anyone know how to differentiate y = root(x) in one go? (secret formula)

yeh maybe L hopitals rule

 

[iampeterr]

You could, its still mathematically correct, but the markets won't know what your doing so I advise you not to.

Sometimes in 3U, 4U students use by parts and at the conference before the marking begins, if someone brings up that what happeneds if 3U students use 4U methods, they will allow it, as long as everyone in that marking group knows what's going on. Still mathematically correct, but unfair for other students I guess.

The 3 unit limits are relatively easy to remember though, aren't they?

btw this isnt a troll post, i just wanted to see if the french method even existed...

Why does everyone consider this some secret formula? Someone at school asked me this as well. If you can differentiate properly, you can do things like that in your head without special 'formulas'

I guess you can memorise this?

Wtf y=x^(1/2) is bring down the power, take one off the power...
