Put the 2D nonlinear system into Polar Coordinates

Click For Summary
SUMMARY

The discussion focuses on converting a 2D nonlinear system into polar coordinates, specifically represented by the equations r′ = r(r^2 − 4) and θ′ = x′1 = x1 − x2 − x1^3, along with x′2 = x1 + x2 − x2^3. The participants emphasize the importance of sharing progress to facilitate effective assistance. This approach ensures that helpers can provide targeted guidance based on the user's current understanding and efforts.

PREREQUISITES
  • Understanding of polar coordinates and their applications in differential equations
  • Familiarity with nonlinear dynamical systems
  • Basic knowledge of calculus and derivatives
  • Experience with mathematical notation and systems of equations
NEXT STEPS
  • Study the transformation of Cartesian coordinates to polar coordinates in dynamical systems

Show that, in polar coordinates, the system is given by
r′ = r(r^2 − 4)
θ′ = 1x′1 = x1 − x2 − x1^3
x′2 = x1 + x2 − x2^3

Hello and welcome to MHB! :D

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?
