Initially, I understood implicit differentiation as soon as I saw it. It just made sense that differentiating y was chain rule outputting the derivative of x. However, as Mr. Cresswell was doing the first example of implicit differentiation of the second derivative on the board, I had no idea what to do. It took me more time than it probably should have to figure out that he was taking the derivative of the first, and plugging it into the dy/dx spots in when taking the second derivative. Once I saw this however, everything seemed so simple. U substitution was another topic this week. Basically if you substitute something for U, and you have the derivative of U, you can write it in terms of du. Count the amount of times "u" was used in that sentence. I just find it interesting how someone can come up with all of these different strategies to solve with substitutions.
