Vector valued scalar function?

Hi (again!)

In the notes my lecturer has given us for line integrals over scalar fields, he talks about "vector valued scalar functions" .

To me this seems contradictory;
I thought a vector valued function was a function taking in either a vector or scalar and outputting a vector, and I thought a scalar function was something outputting a scalar?

Which of these definitions is wrong?
I'm terribly confused and would greatly appreciate any clarification!

Which function was it? I presume its a function taking in a scalar and outputting a vector.

it was actually a function taking a vector outputting a scalar, which makes me wonder if its a mistake

Vector valued generally means the reverse. Why not ask the lecturer?

I don't want to be the one who points out mistakes in his notes I guess I don't make a habit of it I'll do that

Just ask! Think of it as doing your future classmates a favour by clearing up some confusion
