1. The problem statement, all variables and given/known data Hello, I have the following task: 2. Relevant equations In the task 3. The attempt at a solution I looked at this task with the notes from the class, but I can't really see through. It seems that the first step is the transformation into the single decoupled second order differential equation, but I don't actually understand how to do that and at which point I need a program to solve it. Can someone guide me through the solution process?
