Syllabus Description:

Official textbook : Boyce and Diprima, Elementary Differential Equations and Boundary Value Problems or Elementary Differential Equations.
First order differential equations. Autonomous, separable, and linear equations which arise in physics (e. g. motion, mixing problems) and biology (population dynamics).
Second order differential equations. Second order constant coefficient differential equations equations which come up in the study of mechanical and electrical vibrations.
Laplace Transform. A technique which enables us to solve constant coefficient differential equations by converting them into an algebraic problem.
