Non-analytic Smooth Function - Smooth Transition Functions

Smooth Transition Functions

The function

has a strictly positive denominator everywhere on the real line, hence g is also smooth. Furthermore, g(x) = 0 for x ≤ 0 and g(x) = 1 for x ≥ 1, hence it provides a smooth transition from the level 0 to the level 1 in the unit interval . To have the smooth transition in the real interval with a < b, consider the function

For real numbers a < b < c < d, the smooth function

equals 1 on the closed interval and vanishes outside the open interval (a,d).

Famous quotes containing the words smooth, transition and/or functions:

    We are born with luck
    which is to say with gold in our mouth.
    As new and smooth as a grape,
    as pure as a pond in Alaska,
    as good as the stem of a green bean
    we are born and that ought to be enough....
    Anne Sexton (1928–1974)

    Some of the taverns on this road, which were particularly dirty, were plainly in a transition state from the camp to the house.
    Henry David Thoreau (1817–1862)

    The English masses are lovable: they are kind, decent, tolerant, practical and not stupid. The tragedy is that there are too many of them, and that they are aimless, having outgrown the servile functions for which they were encouraged to multiply. One day these huge crowds will have to seize power because there will be nothing else for them to do, and yet they neither demand power nor are ready to make use of it; they will learn only to be bored in a new way.
    Cyril Connolly (1903–1974)
