You should also see also the assigned homework problems on the course web page. Linear algebra ­ The definition of linear independence. Know the definition (see page 248). "Know the definition" means "know the definition," i.e., if you are asked for the definition, then you should be able to state it. Know how to use the definition (in combination with row reduction) to prove a given list of vectors is independent or not (as in examples 5 and 6 on pages 249­250.) Linear algebra ­ subspaces. Know the definition: in this course we have adopted theorem 1 on page 241 as the definition. Be able to prove/disprove that a given set S is a linear subspace of Rn . Be able to find a basis for the solution space of a given set of linear equations (see the algorithm and example on pages 258/259). You should also know the definition of a basis, and you should know the defi- nition of when a set of vectors spans a given subspace. The above topics are covered in the book in §§4.2­4.4. Differential equations ­ first order. You should know how to solve separable equations (y = f(x)g(y), see §1.4) and linear equations (y + P(x)y = Q(x), see §1.5). None of this is new, as you have already seen this material in math 222. Collections: Mathematics
