# Trigonometry

Basic trigonometric functions that aren't offered in BYOND!
 ID:125887   May 13 2011, 9:00 pm 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))/2tan(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)) ``` Code is compressed to smallest size (424 bytes!) in order to have the smallest effect possible on your projects!
