  2. Asymptote - Wikipedia

    en.wikipedia.org/wiki/Asymptote

    A common example of a vertical asymptote is the case of a rational function at a point x such that the denominator is zero and the numerator is non-zero. If a function has a vertical asymptote, then it isn't necessarily true that the derivative of the function has a vertical asymptote at the same place. An example is

  3. Asymptotic analysis - Wikipedia

    en.wikipedia.org/wiki/Asymptotic_analysis

    An illustrative example is the derivation of the boundary layer equations from the full Navier-Stokes equations governing fluid flow. In many cases, the asymptotic expansion is in power of a small parameter, ε : in the boundary layer case, this is the nondimensional ratio of the boundary layer thickness to a typical length scale of the problem.

  4. Sigmoid function - Wikipedia

    en.wikipedia.org/wiki/Sigmoid_function

    A sigmoid function is constrained by a pair of horizontal asymptotes as . A sigmoid function is convex for values less than a particular point, and it is concave for values greater than that point: in many of the examples here, that point is 0.

  5. Curve sketching - Wikipedia

    en.wikipedia.org/wiki/Curve_sketching

    Determine the asymptotes of the curve. Also determine from which side the curve approaches the asymptotes and where the asymptotes intersect the curve. [1] Equate first and second derivatives to 0 to find the stationary points and inflection points respectively.

  6. Asymptotology - Wikipedia

    en.wikipedia.org/wiki/Asymptotology

    In physics and other fields of science, one frequently comes across problems of an asymptotic nature, such as damping, orbiting, stabilization of a perturbed motion, etc. Their solutions lend themselves to asymptotic analysis (perturbation theory), which is widely used in modern applied mathematics, mechanics and physics. But asymptotic methods ...

    One problem also is that seemingly none of the basic algebra books give a good definition (they typically split it into horizontal, vertical, and in some cases oblique linear asymptotes and don’t have a real definition but only a picture and a few examples).

  8. Improper integral - Wikipedia

    en.wikipedia.org/wiki/Improper_integral

    but cannot otherwise be conveniently computed. This often happens when the function f being integrated from a to c has a vertical asymptote at c, or if c = ∞ (see Figures 1 and 2). In such cases, the improper Riemann integral allows one to calculate the Lebesgue integral of the function.

  9. Tractrix - Wikipedia

    en.wikipedia.org/wiki/Tractrix

    The area between the tractrix and its asymptote is ⁠ π a 2 / 2 ⁠, which can be found using integration or Mamikon's theorem. The envelope of the normals of the tractrix (that is, the evolute of the tractrix) is the catenary (or chain curve ) given by y = a cosh ⁠ x / a ⁠ .
