+### RootSegmentVolume
+
+__Registered under__: rootSegmentVolume
+
+__Summary__: Computes the volume of a root segment, or the volume of the steel of a root segment, or the volume of a root segment ignoring RCS, assuming it is either cylindrical or a cut-off cone. 
+
+__Literature references__: -> <https://en.wikipedia.org/wiki/Cone#Volume_2>
+
+__Mathematical formulation (ode, etc)__:  
+Volume of a cylinder $= h * pi * r^2$  
+Volume of a cone $= \frac13\pi \cdot r^2 \cdot h$  
+Volume of a cut-off cone = volume bigger cone - volume smaller cone $= \frac13 \pi (r_1^2 - r_2^2)$
+
+$r =$ cylinder radius, $r_1 =$ radius of larger side, $r_2 =$ radius of smaller side, $h =$ height of cut-off cone/cylinder
+

+### RootSegmentLength
+
+__Registered under__: rootSegmentLength
+
+__Summary__: Computes the length of a root segment, based upon the trajectory of the root tip (not the distance between root nodes, which can be a coarser representation). 
+In particular, the length of a segment equals the length to the next node (the end of the segment) or growth point, minus the length to the current node.
