Difference Quotient - Defining The Point Range

Defining The Point Range

Regardless if ΔP is infinitesimal or finite, there is (at least—in the case of the derivative—theoretically) a point range, where the boundaries are P ± (.5)ΔP (depending on the orientation—ΔF(P), δF(P) or ∇F(P)):

LB = Lower Boundary; UB = Upper Boundary;

Derivatives can be regarded as functions themselves, harboring their own derivatives. Thus each function is home to sequential degrees ("higher orders") of derivation, or differentiation. This property can be generalized to all difference quotients.
As this sequencing requires a corresponding boundary splintering, it is practical to break up the point range into smaller, equi-sized sections, with each section being marked by an intermediary point ("Pi"), where LB = P0 and UB = Pń, the nth point, equaling the degree/order:

LB = P0 = P0 + 0Δ1P = Pń - (Ń-0)Δ1P; P1 = P0 + 1Δ1P = Pń - (Ń-1)Δ1P; P2 = P0 + 2Δ1P = Pń - (Ń-2)Δ1P; P3 = P0 + 3Δ1P = Pń - (Ń-3)Δ1P; ↓ ↓ ↓ ↓ Pń-3 = P0 + (Ń-3)Δ1P = Pń - 3Δ1P; Pń-2 = P0 + (Ń-2)Δ1P = Pń - 2Δ1P; Pń-1 = P0 + (Ń-1)Δ1P = Pń - 1Δ1P; UB = Pń-0 = P0 + (Ń-0)Δ1P = Pń - 0Δ1P = Pń; ΔP = Δ1P = P1 - P0 = P2 - P1 = P3 - P2 = ... = Pń - Pń-1; ΔB = UB - LB = Pń - P0 = ΔńP = ŃΔ1P.

Famous quotes containing the words defining the, defining, point and/or range:

    Art, if one employs this term in the broad sense that includes poetry within its realm, is an art of creation laden with ideals, located at the very core of the life of a people, defining the spiritual and moral shape of that life.
    Ivan Sergeevich Turgenev (1818–1883)

    The industrial world would be a more peaceful place if workers were called in as collaborators in the process of establishing standards and defining shop practices, matters which surely affect their interests and well-being fully as much as they affect those of employers and consumers.
    Mary Barnett Gilson (1877–?)

    Mildred Pierce: You look down on me because I work for a living, don’t you? You always have. All right, I work. I cook food and sell it and make a profit on it, which, I might point out, you’re not too proud to share with me.
    Monte Beragon: Yes, I take money from you, Mildred. But not enough to make me like kitchens or cooks. They smell of grease.
    Mildred Pierce: I don’t notice you shrinking away from a fifty- dollar bill because it smells of grease.
    Ranald MacDougall (1915–1973)

    No doubt, the short distance to which you can see in the woods, and the general twilight, would at length react on the inhabitants, and make them savages. The lakes also reveal the mountains, and give ample scope and range to our thought.
    Henry David Thoreau (1817–1862)
