This course consists of lectures and exercise, and contains the basics of the Fourier transform, special functions, partial differential equations, and the Laplace transform.
The aim is for students to be able to use these methods without hesitation when solving physics problems in the future.

### Student learning outcomes

At the end of this course, students will be able to apply Fourier transform, special functions, partial differential equations, and Laplace transform to problems in physics.

### Keywords

Fourier transform, gamma function, Legendre functions, Bessel functions, Hermite functions, Laguerre functions, partial differential equations, Green functions, Dirichlet problems, Laplace transform

### Competencies that will be developed

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

### Class flow

In lecture class students are sometimes given exercise problems for assessment of understanding.
After every class students should review the topic in the class.
In every exercise class students will be given some problems and solve them.
Solutions will be explained in the latter half of the class.
