Access Index ### Course description and aims

For students who have advanced to the field of mechanical engineering, the following topics on vector analysis, which is essential for learning specialized subjects (mechanics, elastic body mechanics, fluid mechanics, electromagnetics, etc.), are covered:
1) Algebraic operation of vector (scalar product, vector product, etc.)
2) Differentiation of vector (motion of mass point, derivative of vector, etc.)
3) Metrics of curves and surfaces with vectors (Frenet-Seret's law, quadratic surface, etc.)
4) Gradient of scalar field and divergence and rotation of vector field
5) Vector field integral theorem (Gauss theorem, Stokes theorem, etc.)

### Student learning outcomes

At the end of this course, students will be able to:
1) Perform the basic algebra operation of vectors.
2) Understand the differentiation of vectors and apply it to the calculation of particle motion.
3) Understand the metrics of curves and surfaces with vectors, and calculate the values.
4) Understand the gradient of scalar field and the divergence and rotation of vector field, and calculate those values.
5) Solve practical problems using the integral theorems of vector field (Gauss theorem, Stokes theorem, etc.).

### Keywords

vector algebra, differential calculus of vector, gauging of curved line and surface, integral calculus of vector, coordinate transformation, Gauss' theorem, Stokes' theorem, orthogonal curvilinear coordinates

### Competencies that will be developed

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

### Class flow

In the beginning of each class, solutions to exercise problems given in the previous class are reviewed. In the end of the class, students are given exercise problems related to the contents of the lecture. Students should check the course schedule and what topics will be covered beforehand, and it is strongly recommended for students to prepare and review those topics.

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

None required.
