# Trigonometry functions

hello everyone,
well my story is a bit complicated..
since i've entered school i was french educated,
now i'm in my last year and i'm moving to an english school
and i'm in the field GS (general sciences)
the reason for moving schools is that i'm travelling to canada next year
to study "astrophysics"..

anyway my question is:
when i was looking at the trigonometry chapter,
i noticed the SEC and the CSC functions
which i discovered their meanings: secx= 1/cosx
and cscx= 1/sinx

and i was astonished because there's no SEC and CSC in french.
i asked grade 11 students in english schools, they told me that they know it
and i asked french educated students in grade 12.. but they don't know it.

are these functions only used in english?

thanks for any help
joe

Welcome to PF!
These function-names are also used in Scandinavia, and in Germany as well, I believe.

Ah yes, writing 1/cos(x) instead of sec(x) is incomprehensible for you feeble-minded Norwegians...

FEEBLE-MINDED??

You just said that "our" way was "incomprehensible". How typically Norwegian, you're all like John Kerry.

At least we don't speak as odd as you do, era jäkla brusefåtöljer.

:P

brusefåtøljer??

Legend has it that brusefåtölj ("noisy chair", I suppose) is Norwegian for "toilet" (yes, I know it's not true).

Is this some kind of strange, Swedish compliment

After all, as is well known, Swedes still dump their bodily refuse in their backyards..

Where's the Dane to complete this Scandinavian insult session?

It never occurred to me that the Sec and Csc, which are pretty rarely used BTW, were not universal!

I've a surname of Scandinavian descent, can I join in? However the only things I knew how to say in Danish was "hard boiled egg" (and some isolated words from Peter Hoeg novels), and I've forgotten that. You'd have to be incredibly thin skinned to find that insulting.
