Greetings all, I am registering for spring 2016 courses and have one question. I can pick up a math course and I have the option between two courses: 430 Formal Logic vs. 481 Applied Partial Differential Equations. I am a math and physics double major. Course list and description: http://catalog.uic.edu/ucat/course-descriptions/math/ I have taking the intro to diff equations course 220. I think taking further differential equation courses would be a very good idea for me and my future. However, due to time constraints of other courses I cannot take class 480: Applied Differential equations this semester. So my question is: Is there a reason why I should wait and take 480 Applied Differential Equations before I take class 481 Partial Differential Equations? Will I be unprepared for 481 if I do not take 480 first? Or are they completely separate. If so, is there any reason to consider taking Formal Logic over 481 knowing that I am interested in mathematical physics? I would think PDE would help me more.
