Differential Equations II

The frontier of scientific modeling.

一点不卡视频观看一区_一点都不卡的中文视频_中文字幕一本到无线_2017中文字字幕一本Drum vibrations, heat flow, the quantum nature of matter, and the dynamics of competing species are just a few real-world examples involving advanced differential equations.

一点不卡视频观看一区_一点都不卡的中文视频_中文字幕一本到无线_2017中文字字幕一本These models and many others from across the sciences, engineering, and finance have nonlinear terms or several independent variables. Their equations hold many surprises, and their solutions draw on other areas of math like linear algebra and vector calculus.
