1. tangents...
Hi once again...
does anyone know how to find the angle of a triangle in Euphoria?
i know how to do it on the calculator:
tan z = 9/5 .. z = tan-1(1.8) .. z = 60.9 degrees...
BUT euphoria dosen't have tan-1, only tan, which answers 0.03142...
any healp appreciated!
Thanks :)

Euphoria 1.5 has "arctan" to do what you're looking for.
Look out for one of the math libraries that are floating around too.
My mathbag.e is (I think) available via Irv's ftp site.

I tried that before i posted this, but got a wrong answer still. I must
have done that maths wrong somewhere :(
anyway thanks! :)

Hi Mike,
You can use arctan in Euphoria, but the answer is in radians. To get the
answer in degrees, as on your calculator, you should multiply it by 180/P=
i.
-- calculations using arctan
constant Pi =3D 3.14159265359
atom a, b
a =3D 9
b =3D 5
printf(1, "The angles are: %.1f and %.1f degrees.",
arctan(a/b) * 180/Pi & arctan(b/a) * 180/Pi)
while get_key() =3D -1 do =
end while

I looked for matbag.e on Irv's site and didn't found it.... I would
like to have it. Is there another way to get it?

It's probably hidden in a file called "cyrek1.zip", as is the rest of my
Euphoria code, upto the date on the zipfile...
If you still can't get it, ask for it via e-mail.
Some of the routines crash out with extreme values e.g. arccos(-1), but
I'm working on a fix, and I might have a better version available in the
near future.
