Agnew prioritizes applications in science and engineering. The book offers in-depth exploration of:
The problem requires making logical assumptions—such as the plow's speed being inversely proportional to the snow's depth. Remarkably, most of the arbitrary variables cancel out in the math, leaving a fixed start time of approximately 11:23 AM . Agnew’s Wit and Style

The most famous legacy of Agnew's textbook is the now-classic "snowplow problem". It starts snowing heavily and steadily in the morning. A snowplow begins plowing at noon, covering 2 miles in the first hour and only 1 mile in the second. The question seems unsolvable due to a lack of data, but the solution reveals a it started snowing.
Modern educators and textbook authors, such as Stanley J. Farlow and Bob Terrell, frequently cite Agnew’s book as a primary inspiration Agnew’s Wit and Style Google Books often offers

In the vast ocean of mathematical textbooks, few vessels have weathered the storm of curricular change as gracefully as Differential Equations by Ralph Palmer Agnew. First published in the mid-20th century, this text remains a gold standard for clarity, rigor, and practical problem-solving. For students, educators, and self-learners alike, the search for the is more than a quest for a free file—it is a search for a mentor in mathematical form.
