Unformatted text preview: of the problem If you solve problems like this, you can go back to your solution later and study from it. If you don’t solve problems like this, studying from your solutions will be almost impossible. Will you be able to understand the jumble of numbers and equations you wrote five weeks ago? Probably not. Prof. Richard Brown in the math department discusses this in detail in a document he wrote for his calculus course a few years ago; I put it in the homework folder in Blackboard, so you can find it there. Doing this kind of thing helps you study effectively. You only have a few days until the final, and you likely have other finals, too; your study time is finite. So you should study efficiently. I’d say the moral of this is spend more time thinking about the problems you solve before you go on to the next problem. Finally, you should figure out what confuses you most and work on that first. If you know what’s going on conceptually in most problems but you have trouble with the algebraic manipulations, focus on solving the sets of equations that pop up in this course. Circuit problems are ideal for that, as they consist almost entirely of setting up a system of several equations and solving for currents. If you’re okay with the algebra but you have trouble figuring out what to do to begin with, I suggest doing this: look through the problems in one of the chapters of the book (or another book), and assign concepts and equations to each problem. If you can boil each problem down to algebraic manipulations, then you’ve basically solved the problem. And if you don’t have trouble with the algebraic manipulations, save them for later. Just thinking through a problem takes up less time than entirely solving the problem. How I Would Study Perhaps the best way for me to help you study is to tell you what I’d do: When I don’t understand something – or I want to learn something – I grab my textbook and read the relevant material in detail. I have a notebook with me while I read, and I work out the derivations myself, filling in the blanks and noting any questions or confusions I might have. If I’m still really confused after that, I go find another textbook an...
