there is so much room for questions, it's quicker to write the proof than to search an answer. And a readily found answer would, for undergrad, less likely be in proof form, or too distinct for specific topics later on. And the instructor might become suspicious and interogate you, in which case, if the material helped you to understand, that's the point.
