Equations appear frequently in mathematics because mathematicians love to use equal signs... In your case, "mpg = distance/gallons" is best understood as "a formula in the form of an equation", which means that in this instance the two words are interchangeable. Equations and Formulas Sometimes...
x is a variable. You do not have to know what its value is. In that equation you have to find the value of x, so if you already know what x stands for then you know the answer
Different types of equations in mathematics Students may come across these different types of equations in Math, Algebra to be specific: 1. Linear equations Linear means having one line. These are equations of the type Y= ax+b where ‘a’ and ‘b’ are numbers and ‘x’ cannot be zero....

The mathematical methods and the ecological model are one of the important means in the study of ecological economics. In this paper, we study an ecological model arising from ecological economics by mathematical method, that is, study the existence of positive solutions for the fractional ...
The exact boundary controllability of linear and nonlinear Korteweg-de Vries equation on bounded domains was established in (L. Rosier) by means of Hilbert Uniqueness Method. The aim of these notes is to illustrate this approach by numer... L Rosier,F Caroline,M Fulbert,... - 《Esaim Procee...
(2.1) in terms of critical temperature and critical pressure. Note that, at the critical point of a pure component, the first and second derivatives of pressure with respect to pressure at constant temperature are zero. (∂P∂V)Pc,Vc,Tc=(∂2P∂V2)Pc,Vc,Tc=0 It means the ...
As exp:C→C∗ is a homomorphism, this means that logw is a coset with respect to the subgroup K; equivalently, logw, where w≠0, is an element of the quotient group C/K. Note that according to this definition, log0 is defined, and it is the empty set ∅ because,...
3) once we solve for answers we have to check that each works in the original equations; in this way, we eliminate extraneous外部的 roots.(注意注意) Function Notation 1) the notationf(x) = expressionmeansxis the ‘input’. We plug the value ofxinto the expression, and the resultant val...
Potentials of the nonstationary Schr"{o}dinger operator constructed by means of $n$ recursive B"{a}cklund transformations are studied in detail. Corresponding Darboux transformations of the Jost solutions are introduced. We show that these solutions obey modified integral equations and present their ...
