CALCULATOR SYNTAX???

[Chocolate01]

i was wondering if any of u gyz know if calculator syntax is accepted as working out in the exams(esp.for probability - binpdf, bindocdf, normalcdf...). Coz my teachers said it is,yet i heard some teacher's in other schools says it's not.
Thnx gyz

Our teacher tells us to not write it in, but instead using english like "Using calc" eg.


Using calc,

You can write in brackets (Syntax : ... )

Btw, does anyone know whether you have to write fnInt(X^2+X, X, 0, 2) [like with the capital x and the ^) or can you just write in your normal maths writing .

Apparently you cant right syntax, and if you do, the markers have the right to " Deduct " marks..
Don't use syntax, not worth the "risk".

so waht do we write for the binomcdf, normalcdf etc ?

this what i do
say for an eq it says find Probability that a mass weighs more than 100kg

i'd do Pr(X_>100) = then write the probability here

Exactly what the teachers at my school has been saying.

We were told specifically to never ever write probability syntax on the exam.

I agree, I think the reason why calculator syntax should be avoided is because different schools use different calculators, and the VCAA accept different calculators with DIFFERENT syntax. It's hard to give syntax a method mark since it's not uniform, and doesn't really "show off" mathematical skills. With that being said however, if the entire cohort has done extremely poorly on Exam 2, VCAA may change its marking scheme and allow calculator syntax as a methods mark (esp in non-CAS). But I personally wouldn't take the risk, and it helps to understand the theory behind the syntax with some mathematical theory/knowledge...

Is it the same for when we integrate. No writing nInt(...) ?

EDIT: I don't mean as part of the working with an equal sign, I mean in brackets next to the working with (using nInt(...) ). Is that unacceptable too?

Teachers said it was OK to do that, it is just probability they said you shouldn't write the syntax.

Why bother - just write out the appropriate theory (e.g. integral signs or whatever) and then use the calculator to figure it out if need be; you're just wasting your time writing both, esp since calc syntax does not always count as "methods" of acquiring an answer

[NE2000]

OK. Yeah I haven't really ever seen a mark allocated to syntax before. I guess "using calc" in brackets would be sufficient.

Yeap that's what I do on questions which say "Find..." or "Solve to 2 d.p etc etc" or any others.

Do you do CAS or just normal Methods?
Because if you do normal methods like me, there might be hope for some syntax marks haha, but that is if the examiners are desperate to give out marks!

[NE2000]

Normal methods.
