function of n variables
61Separation of variables — In mathematics, separation of variables is any of several methods for solving ordinary and partial differential equations, in which algebra allows one to rewrite an equation so that each of two variables occurs on a different side of the equation …
62Discriminant function analysis — is a statistical analysis to predict a categorical dependent variable by one or more continuous or binary independent variables. It is different from an ANOVA or MANOVA, which is used to predict one (ANOVA) or multiple (MANOVA) continuous… …
63Substitution of variables — In mathematics, substitution of variables (also called variable substitution or coordinate transformation) refers to the substitution of certain variables with other variables. Though the study of how variable substitutions affect a certain… …
64Renal function — Diagram showing the basic physiologic mechanisms of the kidney Renal function, in nephrology, is an indication of the state of the kidney and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid …
65sentential function — noun formal expression containing variables; becomes a sentence when variables are replaced by constants • Hypernyms: ↑formula, ↑expression * * * noun : an expression that contains one or more free variables and becomes a declarative sentence… …
66propositional function — Logic. See sentential function. [1900 05] * * * Sentencelike expression that may be thought of as obtained from a sentence by substituting variables for constants occurring in the sentence. For example, x was a parent of y may be thought of as… …
67Green's function for the three-variable Laplace equation — The free space Green s function for the three variable Laplace equation is given in terms of the reciprocal distance between two points. That is to say the solution of the equation : abla^2 G(mathbf{x},mathbf{x }) = delta(mathbf{x} mathbf{x }) is …
68Massieu function — In thermodynamics, Massieu function, symbol Ψ (Psi), is defined by the following relation: where for every system with degree of freedom r one may choose r variables, e.g. , to define a coordinate system, where X and Y are extensive and intensive …
69Ackermann function — In recursion theory, the Ackermann function or Ackermann Péter function is a simple example of a general recursive function that is not primitive recursive. General recursive functions are also known as computable functions. The set of primitive… …
70Wave function — Not to be confused with the related concept of the Wave equation Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A B) and quantum mechanics (C H). In quantum mechanics (C H), the ball has a wave… …
