Hi Frank,

To do that, you can proceed as follows:


1) write the equation of the coordinates of the circumcenter of a 
triangle in function of the coordinates of the three vertices of the 
triangle

2) compute their derivative


Using matrix derivation rules helps 
(https://tminka.github.io/papers/matrix/minka-matrix.pdf)

I did that in the following article (see in particular the appendix)

Hope this helps,

-- Bruno
