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 traveling 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
