Missing form =ARCCOS

I need the form i calc =ARCOS to make cos 0,7 to 45,57

the form i use ind OpenOffice 2.0.2 (installede) is

=ARCCOS(B1)*360/(2*PI()) and =ARCSIN(D1)*360/(2*PI())

but that form dont work in PortableOffce 2.0.1
They work fine i the installd version (OOo 2.0.2)

im also missin the symbol for sqrt and + when i using Object - forms in Writer, theres just at box instead.
