Does anyone know of some free (downloadable) inverse trig functions for QB? I don't have time to look right now and i can't remember if QB comes with any versions of ASIN, ACOS, ATAN. I could use them. If not i guess i'm going to have to use tables of somesort. Yuck.

A quick search with Google yielded the following definitions:
| Code: | PI = 3.14159265#
DEF FN ACOS(x) = - ATN (x / SQR ( - x * x + 1)) + .5 * PI
DEF FN ASIN(x) = ATN (x / SQR ( - x * x + 1)) |

take a close look. bjorn is merely assigning acos and asin the proper variables. there is no acos and asin. bjorn is showing you how to make your own though.

Take an even closer look, QB does have one built in, the ATAN. :-)

Yeah I know what he was showing, I was simply saying, "oh, QB has a built in ATAN function I didn't know that...". My keywords were one function, as bjorn just said:
