  2. Bernoulli polynomials - Wikipedia

    en.wikipedia.org/wiki/Bernoulli_polynomials

    A periodic Bernoulli polynomial P n (x) is a Bernoulli polynomial evaluated at the fractional part of the argument x. These functions are used to provide the remainder term in the Euler–Maclaurin formula relating sums to integrals. The first polynomial is a sawtooth function.

  3. Note G - Wikipedia

    en.wikipedia.org/wiki/Note_G

    The third column tells the computer exactly what command is taking place, (For example, on line 1, the command performed is "" - the first iteration of variable 2 is multiplied by the first iteration of variable 3.) and only incorporates one operation between two terms per line. Column 4 - "Variables receiving results" takes note of where the ...

  4. Macaulay's method - Wikipedia

    en.wikipedia.org/wiki/Macaulay's_method

    The starting point is the relation from Euler-Bernoulli beam theory = Where is the deflection and is the bending moment. This equation [7] is simpler than the fourth-order beam equation and can be integrated twice to find if the value of as a function of is known.

  5. Logistic regression - Wikipedia

    en.wikipedia.org/wiki/Logistic_regression

    The second line expresses the fact that the expected value of each Y i is equal to the probability of success p i, which is a general property of the Bernoulli distribution. In other words, if we run a large number of Bernoulli trials using the same probability of success p i , then take the average of all the 1 and 0 outcomes, then the result ...

  6. Hydraulic head - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_head

    In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the kinetic energy associated with the speed of flow of the fluid, plus energy from static pressure in the fluid, plus energy from the height of the fluid relative to an ...

    Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

  8. Stream function - Wikipedia

    en.wikipedia.org/wiki/Stream_function

    The x- and y-components of the flow velocity at a given point are given by the partial derivatives of the stream function at that point. The value of the stream function is constant along every streamline (streamlines represent the trajectories of particles in steady flow).

  9. Influence line - Wikipedia

    en.wikipedia.org/wiki/Influence_line

    The slope of the inflection line can change at supports, mid-spans, and joints. An influence line for a given function, such as a reaction, axial force, shear force, or bending moment, is a graph that shows the variation of that function at any given point on a structure due to the application of a unit load at any point on the structure.
