writing csc instead of cosec? (2 Viewers)

[ADrew]

Do you get marked down in the HSC for using the notation 'cscx' instead of 'cosecx'? I just find it neater and could possibly save some space when writing.

Someone correct me if I'm wrong but I believe the syllabus makes it "cosec", so you'll have to write that. If you want to use "csc", you'll have to specify it before - just in case.

HSC markers mark very, very hard - so don't give them a reason to give some doubt to whether they'll give you a mark or not.

Don't risk it, markers might mark you down for it.

Its like an extra 2 letters, geez...

what so hard about writing an extra 2 letters (as the above comment has stated).

theres a fairly good chance that you will never come across "cosec" in a 2unit exam ( possibly 3unit but not that liekly either ) . They usually keep shit fairly easy and just use sin, cos and tan , they like never use the reciprocal ratios , they could possibly in a trig equation question ( ie instead of solve sin(x) = 1/2 they could say solve cosec(x) = 2 ) , but thats pretty unlikely

Yeah lol, csc looks retarded anyway

No it doesn't. Makes for more consistent 3-letter abbreviations for all the 6 trig functions. In a sense, it is stupid for the Board of Studies to insist on that convention. I myself prefer csc. It is also the usage in respected university calculus texts like James Stewart and Thomas & Finney.

But, as suggested, stick to cosec just to be safe.

Ah I see. But this is the HSC derp.

I often tell my students that, contrary to what many think, markers are always looking for reasons (& excuses) to award you marks. (You must help them help you.) But they must have a basis for doing so or else they'll be taken to task for arbitrarily awarding marks. Therefore it is imperative you set out your solution clearly, step by step; each key step can earn you a fractional mark. If you show no steps and get your final answer wrong marker must award you 0. Even with final answer right but without clearly showing your steps, you should get only partial mark.

That's why I said immediately afterwards: so don't give them a reason to give some doubt to whether they'll give you a mark or not.

My teacher for 4unit also said that writing "cis" is also frowned upon.

peter brown at unsw doesnt like it either lol

cosec 1/sin
cot 1/tan
sec 1/cos

it's kind of easier to tell which trig function it's reciprocal to if you write cosec.
so if you're bothered to ask this on BOS , then why wouldn't you be bothered to write the extra two letters?

 

[AAEldar]

I prefer cosec (and it's what I've been taught), I don't like the look of csc. To each their own however.

 

[Trebla]

'csc' is actually the more commonly used notation in practice...

It doesn't actually matter which way you write it. Both are universally accepted notations so there is no way a qualified HSC marker will take marks off for a widely accepted alternative notation of the same thing.

 

[Shadowdude]

I'd go safe, and write the syllabus-approved "cosec".

13.2 The functions sin x, cos x, tan x, cosec x, sec x, cot x and their graphs.

From the Current Maths 2/3u Syllabus.

@OP. Yea, it does takes longer to write cosec but when you time yourself, you're only spending 0.5s extra.

ffs

I have lost 0.5s of my day. Life ruined.

Lol I write cis.
