## Learning outcomes

The aim of the course is to learn how to solve ordinary differential equations of the first and second order. After completing the course, the student

- masters basic terminology related to differential equations
- recognizes and can solve separable equations and separable recoverable equations
- is able to solve the first order linear differential equation
- can solve second order equations that return to the first order
- knows how to apply the ordinal drop to find another solution to a homogeneous equation when one solution is known
- can solve a second order constant coefficient using a homogeneous linear differential equation with a characteristic polynomial
- knows how to find a solution to a second-order linear differential equation by constant variation and constant multiplication by experiment
- is familiar with the series solutions of differential equations
- is familiar with the numerical methods of solving differential equations
