This course has two parts.
In the first part, Fourier transform and partial differential equation are dealt with. These topics are important to understand dynamic problems in the fields of civil engineering. The following topics are discussed: Fourier series, Fourier integral, formulation of partial differential equation, its general solutions, and method of separation of variables.
The second part focuses on vector calculus. Topics include derivative of a vector function, parametric representation of a curve, tangent to a curve and arc length of a curve, gradient of a scalar field, directional derivative, divergence and curl of a vector field, line integrals, Green’s theorem in the plane, surface integrals, divergence theorem of Gauss and Stokes’s theorem.
Vector calculus is important and is essential for the study of engineering. Students learn the basics of vector differential calculus and vector integral calculus and will be able to solve some practical problems in engineering.
By completing this course, students will be able to:
1) Explain the basic theory of Fourier transform.
2) Explain the relationships between frequency and time domain.
3) Formulate and solve some basic partial differential equations.
4) Explain the concepts of scalar fields and vector fields.
5) Calculate line integrals and surface integrals.
6) Proof and use Green’s theorem in the plane, surface integrals, divergence theorem of Gauss and Stokes’s theorem.
