Include the following trigonometric procedures by simply checking the include-box!

Version 1.0 (359 bytes)
*Added all basic functions.

Version 1.1 (401 bytes)
*Added arctan2() function.
*Fixed arcpyth() function.

Version 1.2 (424 bytes)
*Uncompressed for cross-eyes sake. :)

pyth(a,b) return sqrt(a**2+b**2)
arcpyth(a,c) return sqrt(c**2-a**2)
triarea(a,b,C) return (a*b*sin(C))/2
tan(n) return sin(n) / cos(n)
cot(n) return cos(n) / sin(n)
sec(n) return 1 / cos(n)
csc(n) return 1 / sin(n)
arctan(n) return arccos(1 / sqrt(1+n*n))
arccot(n) return arcsin(1 / sqrt(1+n*n))
arcsec(n) return arccos(1 / n)
arccsc(n) return arcsin(1 / n)
arctan2(x,y) return 2*arctan(y/(sqrt(x**2+y**2)+x))
