So Yesterday I did some more math. It was cool because I watched a couple videos about practice problem simulators. They were all very interesting. They took me a long time to actually understand. The first involved moving orange dots that control the derive lines on a graph. It basically provides a visual representation of the derivative on a graph. The orange dots align to form the derivative of the original graph. If an orange line does not connect through the orange dots then I did not make the derivative right. That is how I knew if I got it right. The first few I did not do so well on. Sometimes my directions would be off. But once I got it right it seemed pretty simple, so that was nice. The next practice session was really cool too. It also involved graphs and the goal was to highlight a region of the graph. For example the question would be something like “A function f(x) is plotted below. Highlight an interval where f(x)<0 and f′(x)<0.” After reading the question I would try to pick a section of the graph that fit the description. This practice was really hard for me to get through. I got it ok at first, got a couple correct in a row. Then I was starting to get worse. I guess I just got lucky the first few times. Anyway I did kind of give up on that one. But I will go back to it eventually.

So tonight I worked on it again for an hour. Only got a little better but still could not get it to be five in a row. So the increase in my sufficiency was not that significant. Guess this is something I am going to have to work on a lot more.
