In the classic textbook Differential and Integral Calculus by Florentino T. Feliciano and Fausto B. Uy Chapter 10: Methods of Integration
Veteran instructors often note that Chapter 10 is the point of the semester. Students who master its techniques rarely fail the final exam; those who struggle often repeat the course. As a result, review centers (like the famed MSA or Excel) devote entire sessions to Feliciano-and-Uy Chapter 10 problems, often reprinting them verbatim. In the classic textbook Differential and Integral Calculus
Chapter 10 exemplifies a teaching philosophy that prioritizes . Feliciano and Uy were writing for students who would become practitioners — civil engineers calculating beam deflections, electrical engineers analyzing rates of change in circuits, business students finding break-even points. The chapter does not spend pages proving the Mean Value Theorem (that appears earlier, in Chapter 4). Instead, it shows how to use derivatives to solve a concrete problem. Students who master its techniques rarely fail the
Chapter 10, typically titled or “Further Applications of the Derivative” (depending on the edition), is where the abstract machinery of limits, slopes, and derivatives transforms into a toolkit for solving real-world problems. This feature explores the chapter’s structure, its signature problems, the pedagogical philosophy behind it, and why it continues to challenge and inspire students today. Feliciano and Uy were writing for students who
