Mathematics for the Curious

While do the arms of a clock coincide? How most probably is it that kids within the comparable type will proportion a birthday? How will we calculate the quantity of a doughnut? arithmetic for the Curious offers someone drawn to arithmetic with an easy and enjoyable account of what it could actually do. writer Peter Higgins provides transparent factors of the extra mysterious good points of early life arithmetic in addition to novelties and connections that end up that arithmetic may be relaxing and entire of surprises.

Nonlinear programming

This ebook is an advent to nonlinear programming, written for college kids from the fields of utilized arithmetic, engineering, and financial system. It bargains with theoretical foundations besides assolution equipment, starting with the classical systems and achieving as much as "modern" tools. a number of examples, workouts with distinct recommendations and functions are supplied, making the textual content enough for person reports
