derivative = 0 vanishes and the facade and back walls of House becomes decoupled, as
shown in Figure 1.5.1b.
Let's say, in 1.5.1a two black arrows connect the node, one comes from node through the
operator ( x) and another one comes from node through the operator (− ). Therefore, the
vector is the sum of two
0 0 incoming vectors x
and (− ), i.e. =

that is the 2
