#### Course Description

Introduces differential and integral calculus, with applications to engineering problems, including kinematics, moments of inertia and deflections of beams. Specific calculator required, see advisor. Prerequisites: CMET 121, 122, 123. Audit available.#### Addendum to Course Description

This course is required for all students in the Civil and Mechanical Engineering Technology program, and is a prerequisite for many other CMET courses. Full-time students will generally take this course in their third term of the program.

#### Intended Outcomes for the course

The student will be able to:

- Use differential and integral calculus to solve engineering problems involving rates of change.
- Apply knowledge gained in this course in subsequent engineering courses such as Dynamics, Thermodynamics, or others.
- Communicate analysis and results clearly: orally, in writing, and through diagrams and calculations.
- Work in small groups with individuals of diverse cultural backgrounds

#### Outcome Assessment Strategies

Individual, small group, and full class discussion; homework problems; examinations; and small group problem-solving sessions may be used to assess outcomes.

Lecture, homework, and in-class group activities will be coordinated.

Specific evaluation procedures will be defined during the first week of class. In general, grading will depend on weekly tests, homework, class participation, and a comprehensive final exam.

#### Course Content (Themes, Concepts, Issues and Skills)

- Engineering problems often involve quantities that are changing, and calculus is needed to describe and model that change.
- A mathematical relationship may be described verbally, graphically, numerically, or symbolically; each representation has advantages and disadvantages. A complete analysis of an engineering problem may include several of these approaches.
- Calculus is an essential mathematical tool for engineers and technicians. Even though many people in the engineering field do not frequently solve equations that require derivatives and integrals, a basic knowledge of calculus is necessary for understanding the mathematical background of many relationships that are used.
- Studying calculus opens doors for engineering technicians. Many technical books, articles, and references use symbols and procedures that involve calculus. People who have not studied calculus will often avoid such material because they are intimidated by the unfamiliar symbols and language.
- Studying calculus greatly improves a students algebra skills.
- A large complex problem consists of many inter-related smaller problems which must be solved in a logical order.
- Solution of an engineering problem is not useful unless communicated clearly and completely.
- There is often more than one correct approach to the solution of an engineering problem. Sharing ideas with others will often lead to the most efficient or clearest solution.
