Learning Differential Equations Learning Differential Equations Differential equations is the fourth course in a sequence.
More problems involve multiple steps.
The solution algorithms are considerably more complex. Mistakes and omissions yield either impossible completions or trivial ones that don't merit partial credit for work beyond the mistake. As a consequence of these differences, one needs to change the focus of one's study time away from computations. It may feel good to find the missing minus sign in three pages of algebra, but the half hour that you use to do so would have been better spent reviewing the major steps in the solution and the ideas behind it. You will probably never again drop the minus sign in exactly the same place, so finding it will not help you solve future problems.
