Our college professor is following Lawrence Perko's book for our ODE course, and I have absolutely no clue what he is teaching, as he is randomly doing stuff. I don't like Perko's book because it is not self contained, and does not help in building intuition before doing a particular thing. I want to understand the subject better. Here is our course syllabus for the ODE course:
I want book recommendations that would be relevant, builds things from scratch, and which not just mentions theorems, but also makes it intuitive. P.S. This is my first ODE course.
