### Course description and aims

This course focuses on the Partial differential equations and Laplace transform. Topics include 1st order partial differential equations, 2nd order partial differential equations, Laplace transforms, the properties of Laplace transforms, and solving differential equations with the Laplace transform. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of mathematical tools widely applicable to linear systems in Engineering.
Mathematical approaches, such as solutions of partial differential equations and Laplace transform, taught in this course are not only useful in analyzing problems in mechanical engineering, but are applicable to those in the various field of engineering. Students will experience the satisfaction of solving practical problems by using their mathematical knowledge acquired through this course.
