Can anyone comment on the usefulness of taking differential equations? I'm trying to decide whether or not I should take it next semester. What I've heard is that class is very difficult without having a background in physics (which I do not), as most of the class's focus is on physics applications and rarely delves into economics. I understand that differential equations is used in optimization theory, but if it's mostly focused on physics, then I feel like taking it wouldn't be too helpful and not worth the burden.
If I were to not take it, I could take Calculus 4 next semester instead and be able to fit in Stochastic Processes in the coming year. On the other hand, Differential Eqs, in our school, has 200-level math classes listed as co-reqs meaning if I don't take it this year, I'll never have the chance to take it again.
Any thoughts?
