I am grading differential equations final exams. I have the usual mix…for the most part.
But I have 3 students who are very, very good. And as far as one of these: let’s just say that when he/she writes an answer down that differs from the one I produced for the key…I double check my own work.
And once in a while….I am quietly embarrassed. 🙂
Note: but even this student is confused about numerical methods to solve differential equations; I’ll have to address that (with a post) over break.
