That technique won't scale if you're trying to integrate some crazy complex function.
- eesmith 3y agoA "calculus tyro", as a general rule, is not trying to integrate some crazy complex function as part of a homework assignment.
- xigoi 3y agoIntegrating a piecewise continuous function by splitting it is used all the time.
- justeleblanc 3y agoExam questions have two wonderful property: they have an answer, and the person who wrote it knows that you have the knowledge to find the answer.
- mrguyorama 3y agoNope, good teachers understand when the question they wrote thinking to test certain concepts falls flat, because of some unforeseen oversight or quirk. Something being clear and intuitive to a math professor is not the same as something being clear and intuitive to the students. The best professors strike and ignore questions that "failed", ie didn't accurately test what they thought they would.
- justeleblanc 3y agoI don't quite see how that's relevant to what I said.
- mrguyorama 3y ago>the person who wrote it knows that you have the knowledge to find the answer. This isn't always true. The person who wrote it only knows what they taught, not what you have learned. The point of the test is to find what you have learned. This is just a nitpick I think.
- justeleblanc 3y agoNot a very interesting nitpick then. I guess I should have written "knows that you should have the knowledge to find the answer". If we could teach and be sure that students had learned, we wouldn't need to test them.
- falcor84 3y agoWhich part doesn't scale? From my experience, the technique of looking at the graph of various components in the function has been really useful.
