QUOTE : Now, I like to think that I'm of reasonable intelligence, but ordinary differential equations and myself...we don't really hang in the same comprehension circles. So, try as I might to follow my teacher's logic in how he got 3f"(x) + 5xf(x) to equal eleven, I never quite understood. His answer in no way, shape, or form resembled mine, and this misalignment -this complete confusion of how point A got to point B- is kind of where I'm at right now. "Dreaming?" I repeat dubiously.
