Aitken's delta-squared process is an acceleration of convergence method and a particular case of a nonlinear sequence transformation. A sequence X = ( x n ) {\textstyle X=(x_{n})} that converges to a limiting value ℓ {\textstyle \ell } is said to converge linearly , or more technically Q-linearly, if there is some number μ ∈ ( 0 , 1 ...
The main advantage of Steffensen's method is that it has quadratic convergence [1] like Newton's method – that is, both methods find roots to an equation just as 'quickly'. In this case quickly means that for both methods, the number of correct digits in the answer doubles with each step.
In economics, the price elasticity of demand refers to the elasticity of a demand function Q(P), and can be expressed as (dQ/dP)/(Q(P)/P) or the ratio of the value of the marginal function (dQ/dP) to the value of the average function (Q(P)/P).
In statistics, the delta method is a method of deriving the asymptotic distribution of a random variable. It is applicable when the random variable being considered can be defined as a differentiable function of a random variable which is asymptotically Gaussian .
Starting from the differential equations that describe heat transfer, several "simple" correlations between effectiveness and NTU can be made. [2] For brevity, below summarizes the Effectiveness-NTU correlations for some of the most common flow configurations: For example, the effectiveness of a parallel flow heat exchanger is calculated with:

These equations for solution of a first-order partial differential equation are identical to the Euler–Lagrange equations if we make the identification = ˙ ˙. We conclude that the function ψ {\displaystyle \psi } is the value of the minimizing integral A {\displaystyle A} as a function of the upper end point.
