    Extractions: by Francis Jordan Real Anal. Exchange 22(2), 696713. In this paper we consider a cardinal invarient related to adding real valued functions defined on the real line. Let F be a such a family, we consider the smallest cardinality of a family G of functions such that h+G has non-empty intersection with F for every function h. We note that this cardinal is the additivity, a cardinal invarient previously studied, of the compliment of F. Thus, we calculate the additivities of the compliments of various families of functions including the darboux, almost continuous, extendable, and perfect road functions. We briefly consider the relationship between the additivity of a family and its compliment.

    Extractions: Students are strongly encouraged to participate. Most important classes of real functions are not closed under pointwise limits. (See e.g. continuous functions or Baire class one functions.) But what happens if we consider longer sequences? Then we obtain results that depend on some additional set-theoretical assumptions.

    Extractions: Topics in calculus Fundamental theorem Function Limits of functions Continuity Calculus with polynomials Differentiation Product rule Quotient rule ... Stokes' Theorem In mathematics , a continuous function is one in which arbitrarily small changes in the input produce arbitrarily small changes in the output . If small changes in the input can produce a broken jump in the changes of the output, the function is said to be discontinuous (or to have a discontinuity As an example, consider the function h t ) which describes the height of a growing child at time t . This function is continuous (unless the child's legs were amputated). As another example, if T x ) denotes the air temperature at height x , then this function is also continuous. In fact, there is the dictum in nature everything is continuous . By contrast, if M t ) denotes the amount of money in a bank account at time t , then the function jumps whenever money is deposited or withdrawn, so the function M t ) is discontinuous. For continuity as it is used in topology, see

    Extractions: Tue Oct 14 18:19:43 EDT 2003 Can anyone identify a real-valued function f continuous on [1, infinity) with the following two properties: 1) f eventually dominates any function in the sequence e^x, e^(e^x), e^(e^(e^x)), .... 2) f is defined in some other way than by defining it first at all integers and then interpolating Defining it first for some dense set, like dyadic rationals, and then interpolating, is of course acceptable. That is the standard way to extend the power function, defined by induction, to a continuous function, by identifying the square root with the "one-halfth" power, etc. Unfortunately, a nice way to do this for "tower" rather than "power" is not apparent: 2T1=2, 2T2=4, 2T3=16, 2T4=65536, but what could 2T(3.5) possibly be?

In electronics, they are ratios of current to voltage and of voltage to current; in acoustics, impedance is the ratio of pressure to velocity. When the appropriate electrical network or acoustical region contains no sources of energy, then these ratios have the positive real property. To see this in a mechanical example, we may imagine applying a known force F Z ) and observing the resulting velocity V Z ). In filter theory, it is like considering that F Z ) is input to a filter Y Z ) giving output V Z ). We have The filter Y Z ) is obviously causal. Since we believe we can do it the other way around, that is, prescribe the velocity and observe the force, there must exist a convergent causal I Z ) such that Since Y and I are inverses of one another and since they are both presumed bounded and causal, then they both must be minimum phase. First, before we consider any physics, note that if the complex number
