  2. Slope field - Wikipedia

    en.wikipedia.org/wiki/Slope_field

    Solutions to a slope field are functions drawn as solid curves. A slope field shows the slope of a differential equation at certain vertical and horizontal intervals on the x-y plane, and can be used to determine the approximate tangent slope at a point on a curve, where the curve is some solution to the differential equation.

  3. Negative hypergeometric distribution - Wikipedia

    en.wikipedia.org/wiki/Negative_hypergeometric...

    Negative-hypergeometric distribution (like the hypergeometric distribution) deals with draws without replacement, so that the probability of success is different in each draw. In contrast, negative-binomial distribution (like the binomial distribution) deals with draws with replacement , so that the probability of success is the same and the ...

  4. Isocline - Wikipedia

    en.wikipedia.org/wiki/Isocline

    Fig. 1: Isoclines (blue), slope field (black), and some solution curves (red) of y' = xy. The solution curves are y = C e x 2 / 2 {\displaystyle y=Ce^{x^{2}/2}} . Given a family of curves , assumed to be differentiable , an isocline for that family is formed by the set of points at which some member of the family attains a given slope .

  5. Dirac delta function - Wikipedia

    en.wikipedia.org/wiki/Dirac_delta_function

    More properly, one has ′ = where τ h is the translation operator, defined on functions by τ h φ(x) = φ(x + h), and on a distribution S by [] = []. In the theory of electromagnetism , the first derivative of the delta function represents a point magnetic dipole situated at the origin.

  6. Linear function (calculus) - Wikipedia

    en.wikipedia.org/wiki/Linear_function_(calculus)

    The slope a measures the rate of change of the output y per unit change in the input x. In the graph, moving one unit to the right (increasing x by 1) moves the y-value up by a: that is, (+) = +. Negative slope a indicates a decrease in y for each increase in x.

  7. Van 't Hoff equation - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_equation

    From this plot, − ⁠ Δ r H / R ⁠ is the slope, and ⁠ Δ r S / R ⁠ is the intercept of the linear fit. By measuring the equilibrium constant , K eq , at different temperatures, the Van 't Hoff plot can be used to assess a reaction when temperature changes.

  8. Slope - Wikipedia

    en.wikipedia.org/wiki/Slope

    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.

  9. Lambert W function - Wikipedia

    The product logarithm Lambert W function plotted in the complex plane from −2 − 2i to 2 + 2i The graph of y = W(x) for real x < 6 and y > −4. The upper branch (blue) with y ≥ −1 is the graph of the function W 0 (principal branch), the lower branch (magenta) with y ≤ −1 is the graph of the function W −1. The minimum value of x is ...
