Wait, maybe the user is a student in a Mexican university? Because "Matemáticas 2" is part of a series used in some educational programs there. The book is written by various authors, sometimes Dennis G. Zill. If they're referring to Zill's Calculus book, that's a common textbook. But the title might be translated differently. Let me check the correct title in Spanish. It's possible they're looking for "Matemáticas 2: Cálculo Integral" by Dennis G. Zill and others.
