**What This Document Is**
This document is a past exam for Math 128, Calculus II, administered at Washington University in St. Louis during the Fall 2009 semester. It’s designed to assess student understanding of key concepts covered in the course, focusing on multi-variable calculus and optimization techniques. The exam format consists of multiple-choice questions, requiring students to demonstrate both computational skills and conceptual grasp of the material.
**Why This Document Matters**
This exam is an invaluable resource for students currently enrolled in or preparing for Calculus II. It provides a realistic assessment of the types of questions and the level of difficulty they can expect on their own exams. Working through similar problems (available with full access) can significantly improve problem-solving speed, accuracy, and overall confidence. It’s particularly useful for identifying areas where further study and practice are needed. Students who utilize past exams often perform better due to increased familiarity with the instructor’s testing style and emphasis on specific topics.
**Common Limitations or Challenges**
While this exam offers excellent practice, it’s important to remember that it represents a specific instance of the course content. Subsequent semesters may cover topics with slightly different emphasis or utilize alternative problem-solving approaches. This exam does *not* include detailed solutions or explanations; it serves as a practice tool, and full understanding requires independent work or access to course materials. It also doesn’t cover *all* possible topics within Calculus II.
**What This Document Provides**
* A set of multiple-choice questions covering core Calculus II concepts.
* Problems relating to optimization of functions of multiple variables.
* Questions involving constrained optimization within defined regions.
* Problems testing understanding of partial derivatives and critical points.
* Application problems involving economic modeling (specifically, production and cost optimization).
