An endogenous variable is one whose value(s) is(are) determined within the system while an exogenous variable is one whose value is determined outside the system. For instance, in some simple Economic models, ...

... Linear algebra has roots which date back as far as the birth of calculus. In the late 1600’s, Leibnitz used coefficients of linear equations in much of his work, and later in the 1700’s Lagrange further developed the idea of determinants through his Lagrangian multipliers. The term “matrix” wasn’t a ...

... (a) Show that if A ∼ B (that is, if they are row equivalent), then EA = B for some matrix E which is a product of elementary matrices. Proof. By definition, if A ∼ B, there is some sequence of elementary row operations which, when performed on A, produce B. Further, multiplying on the left by the co ...
