UZB 218E - Kısmı Differensiyel Denklemlere Giriş_2018

Dersin Amaçları

Students are introduced with linear partial differential equations through simple models, namely, the heat and wave equations, which describe a broad range of scientific phenomenon. Equations are formulated carefully from physical principles, motivating the mathematical solution techniques. Only exact solution methods are discussed.
