The main objective of the course is that the students acquire the ability to use differential equations to model physical phenomena, analyze their properties, solve such equations and use the solutions to deeper understanding of these phenomena. In particular, students will be able to

• Model physical phenomena with ordinary differential equations, partial differential equations and systems of differential equations ,
• Solve such as the above mentioned equations using analytic or graphical methods ,
• Analyze and communicate the results above mentioned results.
• Show clear understanding on Fourier Series analysis and Laplace transforms.
• Ability to use software systems like the http://www.wolframalpha.com/ and http://www.math.uiuc.edu/iode/ for all the above.
