stigma Posted March 25, 2007 Share Posted March 25, 2007 (edited) Hey, Im trying to figure out what the autoit function is for calculating inverse consinus. Its been a long time since I did any school math around this so I am not sure if Acos is the same as inverse. Can someone please clarify for me? =) -Stigma Edited March 25, 2007 by stigma Link to comment Share on other sites More sharing options...

jvanegmond Posted March 25, 2007 Share Posted March 25, 2007 (edited) I think 'inverse cosinus' is a Dutch / European way of pronouncing 'arc cos'.. $pi = 3.14159265358979 $degToRad = $pi / 180 $y = Sin(90 * $degToRad) ;sine of 90° $x = ASin($y) / $degToRad MsgBox(0, $y, $x) Edited March 25, 2007 by Manadar github.com/jvanegmond Link to comment Share on other sites More sharing options...
Uten Posted March 25, 2007 Share Posted March 25, 2007 According to my favorite text book on all math I have forgotten (turns out to be about everything), your right @manadar. ACos, "arc cos" or cos-1(x) is the same as "inverse cos" in the domain 0<=x<=PI. Please keep your sig. small! Use the help file. Search the forum.
