For the system (2a) and (2b), show that any trajectory starting on the unit circle x 2
Question:
For the system (2a) and (2b), show that any trajectory starting on the unit circle x2 + y2 = 1 will traverse the unit circle in a periodic solution. First introduce polar coordinates and rewrite the system as dr/dt = r(1 - r2) and -dθ/dt = -1.
Transcribed Image Text:
dx dt dy dt = y + x - x(x2+y2), = x + y - y(x2+y^2) (2a) (2b)
