Inverse consinus

[stigma]

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? =)

Trigonometric function at wikipedia.

Edit: erm, did not totally compute that question, sorry.

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)

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.

Thanks. now I dont have to question myself every step while debugging my code =P
