Overview of Differential Equations and Linear Algebra
Differential equations are mathematical equations that relate some function with its derivatives. They are crucial for modeling dynamic systems in various fields such as physics, biology, economics, and engineering. Linear algebra, on the other hand, deals with vectors, vector spaces, linear transformations, and systems of linear equations. The synergy between these two areas of mathematics is profound, as many problems in differential equations can be solved with linear algebra techniques.
