What to review from linear algebra for a differential equations class?

AI Thread Summary
To prepare for a summer class in ordinary differential equations (ODEs), a solid review of linear algebra concepts is essential. Key topics to focus on include eigenvalues, diagonalization, and the Jordan canonical form, as these are crucial for understanding systems of differential equations. Familiarity with matrix operations and the matrix exponential is also beneficial. Basic concepts such as bases, linear transformations, determinants, vector spaces, and subspaces should be revisited, as they frequently appear in ODE contexts. While some students may not have formally covered canonical transformations, understanding the foundational elements of linear algebra will significantly aid in grasping the material in differential equations. Resources like Paul's Online Math Notes can provide valuable insights into the relationship between linear algebra and differential equations.

I'm going to be taking a class in ordinary differential equations over the summer and have about 2 weeks to prepare. The class has linear algebra as a prerequisite, and I just wanted to know what I would need to review from linear algebra to prepare myself for the course?

Depends on the course of course. But I think that review eigenvalues, diagonalization and the Jordan canonical form would be ideal.
Maybe you can even review the matrix exponential (or study it if you haven't seen it, it's not too hard).
 
the absolutely basic stuff to review is bases, and the fact that the general solution to a linear equation of form Lx = y, is formed from a particular solution plus a general solution of the corresponding homogeneous equation Lx = 0.
 
So just matrix algebra and eigenvalues/eigenvectors would suffice? What about things like vector spaces, subspaces, spanning sets, and bases? Or linear transformations/mappings and determinants?

Also, I didn't cover canonical transformations which is covered in the linear algebra II class that I haven't taken yet.
 
I'm taking Differential Equations now. At my school, LA is just suggested, not required, for DE, but we have definitely run into LA concepts such as determinants of matrices, linear independence, bases of functions, etc.
