vex to access surface tangents?

I want to use the u or v tangents of a NURBS surface in an attribute wrangle node.  What are the names for the tangents?

 

Well, I found the polyFrame node.  It doesn't play nice with NURBses, not surprisingly, but if I switch to poly geo I get some tangents.  I still want to know how to access the tangents of a NURBS surface, but at least I'm back in business now...
