Lesson 3 of 4 for Passport to Advanced Math. Students will solve systems of equations in two variables in which one equation is linear and the other equation is quadratic or another nonlinear equation; relate properties of the function f...

A discussion on how to solve linear and nonlinear inequalities is presented. Both the Test Method and the Factor Method of checking positive/negative intervals are included as part of the discussion.

A summary of error and uncertainty considerations, presented at an annual mathematicians' meeting. Not terribly deep, and covers the gamut of concerns about modeling of the real world with inadequate data or math tools. On target. This...

Olga Alexandrovna Ladyzhenskaya (1922-2004) is profiled, who worked in linear, quasilinear, and nonlinear partial (and some ordinary) differential equations of elliptic, parabolic, and hyperbolic types, with some theoretical applications...
