Hi,
I can't see the acos function when adding a formula parameter in property set definitions. Isn't it available?
Using AutoCAD MEP 2015
Thanks

No it is not.
VBScript does not have an arccos or arcsin function. It does have an arctan function though so you need to express it in terms of arctan.
ArcSin = Atn(X / Sqr(-X * X + 1))
ArcCos = Atn(-X / Sqr(-X * X + 1)) + 2 * Atn(1)
I believe that my formulas are correct but you might want to double check.
