No, they aren't progressive, although they will have at least one point in common. I believe that this is on the progressive slide because it is in the progressive section in the book. > 3. What advantage do we gain by including one or both endpoints as nodes? This will be useful when we do ordinary differential equations. We will have either initial or boundary data in these cases.
