  2. Zisman Plot - Wikipedia

    en.wikipedia.org/wiki/Zisman_Plot

    The x-intercept lands at 39.5 dynes per centimeter (This can be calculated by setting y equal to zero and solving for x) which is less than that of liquid 2, 42.9 dynes per centimeter; therefore, a more accurate measurement of the critical liquid surface tension needed to effectively wet the surface of PC can be obtained by including liquid 2 ...

  3. Newton's method - Wikipedia

    en.wikipedia.org/wiki/Newton's_method

    The idea is to start with an initial guess, then to approximate the function by its tangent line, and finally to compute the x-intercept of this tangent line. This x-intercept will typically be a better approximation to the original function's root than the first guess, and the method can be iterated. x n+1 is a better approximation than x n ...

  4. Gran plot - Wikipedia

    en.wikipedia.org/wiki/Gran_plot

    Figure 2 gives an example; in this example, the two x-intercepts differ by about 0.2 mL but this is a small discrepancy, given the large equivalence volume (0.5% error). Similar equations can be written for the titration of a weak base by strong acid (Gran, 1952; Harris, 1998).

  5. Inverse demand function - Wikipedia

    en.wikipedia.org/wiki/Inverse_demand_function

    The marginal revenue function is the first derivative of the total revenue function or MR = 120 - Q. Note that in this linear example the MR function has the same y-intercept as the inverse demand function, the x-intercept of the MR function is one-half the value of the demand function, and the slope of the MR function is twice that of the ...

  6. Standard addition - Wikipedia

    en.wikipedia.org/wiki/Standard_addition

    The silver concentration in the test sample is the x-intercept of the plot. The dilution factor is multiplied by this initial concentration to determine the original concentration. Matrix effects occur even with methods such as plasma spectrometry, which have a reputation for being relatively free from interferences. As such, analyst would use ...

  7. Secant method - Wikipedia

    en.wikipedia.org/wiki/Secant_method

    Starting with initial values x 0 and x 1, we construct a line through the points (x 0, f(x 0)) and (x 1, f(x 1)), as shown in the picture above.In slope–intercept form, the equation of this line is

  8. Sight reduction - Wikipedia

    en.wikipedia.org/wiki/Sight_reduction

    In astronavigation, sight reduction is the process of deriving from a sight (in celestial navigation usually obtained using a sextant) the information needed for establishing a line of position, generally by intercept method.

  9. Scatchard equation - Wikipedia

    en.wikipedia.org/wiki/Scatchard_equation

    Mathematically, the Scatchard equation is related to Eadie-Hofstee method, which is used to infer kinetic properties from enzyme reaction data. Many modern methods for measuring binding such as surface plasmon resonance and isothermal titration calorimetry provide additional binding parameters that are globally fit by computer-based iterative ...
