Announcements Bring your clickers on Thurs Jan 29. We will start using them. Do not forget to register these clickers by midnight, tonight (so far, 30 more people to go). WebAssign 1 is due this coming Thurs, also by midnight. . Lecture 04
Some issues to resolve re: notation, what it means to solve a differential equation, etc. 1. What do the following mean: y , y ′′ , etc? The presumption is that the independent variable is x and thus we are deriving with respect to x 2. What does it mean to “Solve the following DFQ...”? Find the explicit function y = y ( x ) which satisfies the given differential equation (or the given Initial Value Problem). It could also be an implicit solution of the form F ( x , y ) = C 3. What is this course? In some sense it is a series of “cook book” recipes to solve various forms of differential equations.. with an added layer of modeling .. and intepretation. So whenever possible, we will give a “tag” (or name) to each method as a sort of guide as to how one should proceed.
