I'm not sure if this should go in this section or the learning materials section, so please feel free to move this thread to the appropriate location. This semester I am taking differential equations. I have a totally awesome professor :) So far we have been working on linear algebra and solving first order ODE's but I noticed that the very first part of the book was about modeling and we did not cover that. The book also does not go into great detail which leads me to wonder if this is something I should have learned in Calc I or II. So my questions: 1) Should I have learned more about modeling prior to this class? If so, which class should it have been covered in? (I will go back and reference materials) 2) Are there any good resources you can recommend that covers modeling? I appreciate your help with this!
