The more I teach linear algebra, the more I think that perhaps it -- and not calculus -- ought to be the standard introductory math course for those majoring in “technical” fields (science ...

Many data are suitably modeled by functions consisting of straight-line segments. These functions may be called piecewise-linear. Smooth functions that are related to the hyperbola and that have ...

In this problem, the optimal path is one that maximizes the expected utility, with the utility function being piecewise-linear and concave. Such a utility function can be used to approximate nonlinear ...
