+AD4- The code charts tells that U+-0308 Combining di+AOY-resis may be used for
+AD4- indicating the +IBw-double derivate.+IB0- I have only heard people calling this
+AD4- the +IBw-second derivate+IB0gFA-is +IBw-double derivate+IB0- a valid name for this?

The second derivative d/dt ( d/dt ( something )) is got by differentiating
the first derivative d/dt ( something ) another time.
So the something is differentiated twice, that is double.
So yes, it is a valid name.

+AD4- Stefan
