NOTES:

1. Due to our procedures for verifying errata, the date that an entry is updated may be significantly later than the date that the errata was brought to our attention.

2. Sometimes many contributors bring the same errata to our attention.

3. The .pdf and .ps versions of this errata list include an index of dates of when the errata were updated.

FOOTNOTE: An alert reader will wonder how these errors could have occurred, since the integrals in the 30th edition of this book have been electronically verified. The error occurred in the typesetting of the integrals--not in the electronic verification of the integrals. In this section on definite integrals, there are 11 integrals in which there were two integrals on the same line; in all cases the limits on the first integral were (sometimes incorrectly) printed as the limits on the second integral. This resulted in the errors listed above.

A system is said to be controllable if and only if for any times and any states there exists a control such that and . The system is controllable if and only if rank .
