I am looking for a good book to study ordinary differential equations.
My background is that I have successfully completed calculus 1 through 3. So this included derivatives and integrals, multivariable , taylor series, some vector calculus etc.
I have also had two semesters of linear algebra which included basic geometry, matrices, vector spaces, linear transformations, inner product spaces etc.
I am looking for either a good book for self study, or/ and one with good problems.
I am also very open to hearing any opinions on the course in general. Is there anything I should make sure I am completely brushed up on? I have heard a few mixed reviews about the class. Some have said that the class is easy but "boring" and others have said it can be quite difficult.
Anyways, hope all is well, Thanks!
