OK, I got an exam in about a week, and there is a point that I don't really got my head around yet. Our professor likes to give for example three pictures and one differential equation.
The question now is which of these pictures approximates the given equation.
How would I go and start such a task? These are very simple equations and most will probably find this trivial, but as someone in second semester I always get stuck on these kind of questions.
Examples would be:
$$ y^\prime = y + 1 $$
$$ y^\prime = -2xy^2 $$
