To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...

Control and inverse problems in wave equations and graphs constitute a dynamic field at the intersection of applied mathematics, engineering and physics. This area investigates how waves propagating ...

Journal of Applied Econometrics, Vol. 10, No. 2 (Apr. - Jun., 1995), pp. 187-200 (14 pages) We propose a general strategy to estimate semi-parametrically simultaneous equations with limited dependent ...
