##### Module Details
• Application of mathematics in the solution of engineering problems
• Formulation of mathematical models for the solution of engineering problems
• In the end of the class the students should be able to:

• Find general and particular solutions of first order differential equations.
• Solve second order linear differential equations with constant coefficients
• Use the method of power series for the solution of linear differential equations
• Find and use appropriately the solutions of the Bessel and Legendre differential equations.
• Use the Laplace transform and its inverse for the solution of ordinary differential equations
• Solve linear systems of ordinary differential equations with constant coefficients
• Investigate the qualitative behavior of the solution of a non-linear differential equation without solving it
