Can you write cis in the hsc? Thankyou!
Agreed, unless it says to 'express your answer in modulus-argument form' or somethingTbh, I don’t see the point of using the short-hand ‘cis’ when the exponential form is just as convenient (and technically shorter)
Should be -- there's not gonna be any marker who doesn't know what cis means.bruh i use cis every single time...
will i be fine?
Yeah you’re finebruh i use cis every single time...
will i be fine?
I tend to use exponential hut the only problem with it is it’s so small that I sometimes just lose numbers because of handwriting which isn’t really idealTbh, I don’t see the point of using the short-hand ‘cis’ when the exponential form is just as convenient (and technically shorter)
There are some markers who passionately hate cis... though that's more likely to be an issue in trials than in the HSC, where the markers will be required to conform to the same standards.Should be -- there's not gonna be any marker who doesn't know what cis means.
Just make sure it doesn't look too similar to cos (I tend to do that occasionally)

never knew that was a thing, cheersThere are some markers who passionately hate cis... though that's more likely to be an issue in trials than in the HSC, where the markers will be required to conform to the same standards.
Making "cis" and "cos" clearly different is important, though.

That’s probably because ‘cis’ is not a standard or commonly used notation in mathematics. It is rarely seen outside the HSC. Everyone else just uses the exponential form (note that “exp( )” is standard notation) or the full mod-arg form. I don’t think I’ve ever seen ‘cis’ used in uni maths.There are some markers who passionately hate cis... though that's more likely to be an issue in trials than in the HSC, where the markers will be required to conform to the same standards.
