Among them, the adjacent definition domain needs to have two equations F1 and F2 to describe, but the equation is continuous at the boundary point. Me
They often write them as follows:
f (x) = f1 (x) for x = f (x) = f2 (x) for x> = a Smart readers will find that two defined domains overlap at points, but F1 (a) = f2 (a) is established at overlap, So there is no ambiguity in semantics.
