One of the fields where considerable progress has been made is the solution of differential equations. Here we first give an overview of the types of differential equations that R can solve, and then demonstrate how to use R for solving a 2‐Dimensional partial differential equation.

In this course, we start with 2x2 systems. In order to understand most phenomena in the world, we ne The laws of supply and demand help to determine what the market wants and how much. These laws are reflected in the prices paid in everyday life. These prices are set using equations that determine how many items to make and whether to rais The key to happiness could be low expectations — at least, that is the lesson from a new equation that researchers used to predict how happy someone would be in the future.
