Ask and You Will Succeed is a breath of fresh air in a marketplace crowded with advice on what to believe and how to live. Filled with powerful questions that invite you to listen to your inner voice and tap into the strength you need to create your ideal life, this book makes you the final authority in your own life—not outside forces that you can't control.

Ordinary Differential Equations is based on the author's lecture notes from courses on ODEs taught to advanced undergraduate and graduate students in mathematics, physics, and engineering. The book, which remains as useful today as when it was first published, includes an excellent selection of exercises varying in difficulty from routine examples to more challenging problems. These exercises show extensions of the techniques in question and serve to introduce the reader to the literature in this area. New to this SIAM Classics edition is an Errata section listing corrections to minor errors in the 1982 edition. An extensive bibliography (up to 1980) is provided.
