Ordinary Differential Equations

Apply Ordinary Differential Equations to Model and Solve Real-World Problems in Physics, Engineering, and Biology

The Ordinary Differential Equations (ODEs) course introduces students to the theory and techniques of solving and analyzing ordinary differential equations. It covers first-order and second-order ODEs, exploring separable, linear, and exact equations, as well as series solutions. Students learn Laplace transforms and their applications to solve ODEs and understand stability analysis for systems of ODEs. Real-world applications are emphasized throughout, including problems in science and engineering, such as heat conduction and population dynamics. Numerical methods may be introduced to approximate solutions when analytical methods are challenging.

By the end of the course, students gain proficiency in solving ODEs and using them to model various natural phenomena, enabling them to apply these skills to a wide range of practical problems in various disciplines.
