Hopefully, these students will remember important concepts for some time beyond the final exam.

Then there are no free variables in this equation, and so A has n pivot columns. In Theorem 4, statement a is false if and only if statement d is also false. See Theorem 7 b. After many days, a specific student is ill with probability. In particular, x4 is free and not zero as some may assume. Later, the students use these sheets when studying for exams. It is possible to delete column 1or 2 of A instead of column 3. See the Rank Theorem. The correspondence from the list of eight boundary temperatures to the list of four interior temperatures is a linear transformation. See the remark about Example 1 d , following the solution of Example 1. The text does not provide much practice determining whether a transformation is linear, because the time needed to develop this skill would have to be taken away from some other topic.

Any constant nonnegative multiple of these prices is a set of equilibrium prices, because the solution set of the system of equations consists of all multiples of one vector. Example 3 is the background for Exercise 26 in Section 6. Some counterexample is needed. The remaining variable x2 is free. The entries in Px are nonnegative since P and x have only nonnegative entries. See the box after the definition of elementary row operations, in Section 1. By Theorem 17, the solution space is two-dimensional, so the two linearly independent signals. Then r j contains the weights needed to construct the j th column of A from the pivot columns of A, as is discussed in Example 9 of Section 4. See the paragraph following the box that contains equation 4. The basic variables are x1, x3, and x6; the free variables are x2, x4, and x5. The order of the factors for Y is crucial. The ratios of the prices remain the same, no matter what currencyis used. Inspect how the columns a1 and a2 of A are related. Since A is triangular, its eigenvalues are obviously 4 and 2. Use the basic definition of Ax to construct A.
