I actually have little issue w/ learning abstract concepts like rewriting functions as series. But my classmates often cite that as a reason they shouldn't bother putting in the time to really learn it. I'm saying that a good way for teachers to engage students more is to show them examples that actually have some reflection on the real world, so that they can't say "this is totally useless. I won't bother learning it."
