    Extractions: real function (Topic) A real function is a function from a subset of to Without imposing extra conditions, there is really not much one can say about real functions. Therefore, the usual procedure is to select some subclass of real functions according to some criterion such as differentiability or integrability and focus attention on this subclass. There follows a list of such criteria:

    Extractions: Next: NARROW-BAND FILTERS Up: One-sided functions Previous: FILTERS IN PARALLEL Two similar types of functions called admittance functions Y Z ) and impedance functions I Z ) occur in many physical problems. 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

    Extractions: Newton's method works for convex real functions (Theorem) Theorem Let be a convex differentiable function on an interval , with at least one root . Then the following sequence obtained from Newton's method will converge to a root of , provided that and for the given starting point Obviously, ``convex'' can be replaced by ``concave'' in Theorem The proof will proceed in several steps. First, a simple converse result: Theorem Let be a differentiable convex function , and be the sequence in Theorem . If it is convergent to a number , then is necessarily a root of Proof . We have (The first limit is zero by local boundedness of at , which follows from being finite and monotone We claim that whenever , then too. Recall that the

The Periods of the Bulbs " by Robert L. Devaney The Mandelbrot set is built by iterations of function (map) for complex z and c . Iterations begin from starting point z o (usually z o = + i For real c and z o , z m are real too and we can trace iterations on 2D (x,y) plane. To plot the first iteration we draw vertical red line from x o toward blue curve y = f(x) = x + c , where y = f(x o ) = c drag mouse to change the C value To get the second iteration we draw red horizontal line to the green y = x line, where

    Extractions: (Limits of functions) We now introduce the second important idea in Real analysis. It took mathematicians some time to settle on an appropriate definition. See Some definitions of the concept of continuity Continuity can be defined in several different ways which make rigorous the idea that a continuous function has a graph with no breaks in it or equivalently that "close points" are mapped to "close points". For example, is the graph of a continuous function on the interval ( a b while is the graph of a function with a discontinuity at c To understand this, observe that some points close to c (arbitrarily close to the left) are mapped to points which are not close to f c We will give a definition in terms of convergence of sequences and show later how it can be reformulated in terms of the above description. Definition A function f R R is said to be continuous at a point p R if whenever ( a n ) is a real sequence converging to p , the sequence ( f a n )) converges to f p Definition A function f defined on a subset D of R is said to be continuous if it is continuous at every point p D Example In the discontinuous function above take a sequence of reals converging to c c .) Then the image of these gives a sequence which does not converge to f c We also have the following.
