In the previous chapter, we talked about ordinary differential equation initial value problems. We can see that in the initial value problems, all the known values are specified at the same value of the independent variable, usually at the lower boundary of the interval, thus this is where the term ‘initial’ comes …

Webb10 maj 2016 · Boundary conditions (BC) have long been discussed as an important element in theory development, referring to the “who, where, when” aspects of a theory. However, it still remains somewhat vague as to what exactly BC are, how they can or even should be explored, and why their understanding matters.
