Arc cosine

Does anyone have any code for trig functions, specifically the arc cosine? The apple website has Applescript code for sine, cosine and tangent. But not for arc cosine. I am not a math whiz and I thought that before I tried to write something, maybe someone would have allready created it or know where I could look to find it. I am trying to avoid OSAX, as the final script would need to be used on many different machines.

Any help would be greatly appreciated, thanks.

Maybe this will help. I’m no math whiz either so I don’t know for sure. :stuck_out_tongue:
