matrix (@+x k @W rec) is just ˙(xk 1). Equation (5) also provides the form of Jacobian matrix @x i @x i 11 for the speci c parametrization given in equation (11), where diagconverts a vector into a diagonal matrix, and ˙0 computes the derivative of ˙in an element-wise fash-ion. Note that each term @E t @ from equation (3) has the

3. b. The matrix is already in reduced row-echelon form. The nonleading variables are parameters; x2 =r, x4 =s and x 6 =t. The ﬁrst equation is x1 −2x2 +2x4 +x 6 =1, whence x1 =1+2r−2s−t. The second equation is x3 +5x4 −3x 6 =−1, whence x3 =−1−5s+3t. The third equation is x 5 +6x 6 =1, whence x " # → " # → " #

5. If Ais the matrix of an orthogonal transformation T, then the columns of Aare orthonormal. 6. The transpose of an orthogonal matrix is orthogonal. 7. The product of two orthogonal matrices (of the same size) is orthogonal. 8. If Ais the matrix of an orthogonal transformation T, then AAT is the identity matrix. 9.
