apply part (b) or (c) of Exercise 26 tofind the standard matrix of the transformation.27. Reflection in the line y 2x

Step 1 of 5) Notice how alike the formulas are to those in Tables 14.1 and 14.2 for double and triple integrals. The double integrals for planar regions, and the triple integrals for solids, become line integrals for coil springs, wires, and thin rods. Notice that the element of mass dm is equal to d ds in the table rather than d dV as in Table 14.1, and that the integrals are taken over the curve C.
