Sketching simple coupled oscillators

In summary, the conversation discusses how to hand sketch solutions for a given problem without using an explicit solution, by finding an expression for dy/dt and using it along with dx/dt to generate pairs of (x,y). The conversation also mentions that the OP would need to think about what dx/dt and dy/dt represent in order to create the table correctly. The conversation ends with a request for the OP to repost the question in a different section with more details.

If I'm given dx/dt = 2π - sin(y - x), dy/dx = 2π - sin(x - y), and finally the conditions x(0) = pi/2 and y(0) = 0,
what would be the best way to hand sketch the solutions without using an explicit solution?

Find an expression for dy/dt. This seems like a homework problem, so I won't tell you exactly how to do that, but you have the information you need to do that.

Then use your expressions for dx/dt and dy/dt to generate pairs of (x,y) for increasing t, you know what to start from, as its a given in your problem. You need to think about what dx/dt and dy/dt represent to make the table correctly.

Thread closed. The OP has been asked to repost the question in one of the Homework & Coursework sections, using the homework template to include the efforts so far.
 

1. What is a simple coupled oscillator?

A simple coupled oscillator is a physical system made up of two or more oscillators that are connected or coupled together, meaning they influence each other's motion. Examples of simple coupled oscillators include a mass-spring system or a pendulum system.

2. What is the purpose of sketching simple coupled oscillators?

The purpose of sketching simple coupled oscillators is to visually represent and understand the behavior and motion of the system. By sketching the oscillators, we can see how they are connected and how they affect each other's movement.

3. How do you sketch a simple coupled oscillator system?

To sketch a simple coupled oscillator system, you can start by drawing the individual oscillators and their connections. Then, you can add arrows to show the direction of motion and label any important parameters such as mass, spring constant, or damping coefficient. It is also helpful to include a graph of the displacement or velocity of each oscillator over time.

4. What are some important features to look for when sketching simple coupled oscillators?

Some important features to look for when sketching simple coupled oscillators include the natural frequencies of each oscillator, the amplitude and phase differences between the oscillators, and any patterns in the motion of the system. It is also important to consider the initial conditions and any external forces acting on the system.

5. How does the behavior of simple coupled oscillators change with different parameters?

The behavior of simple coupled oscillators can change significantly with different parameters such as mass, spring constant, and damping coefficient. These parameters can affect the natural frequencies of the oscillators and the strength of the coupling between them. Changing these parameters can result in different types of motion, such as beating, resonance, or chaotic behavior.
