Figure 2
From: Weak and strong singularities problems to Liénard equation
The first picture shows the system response in the \((x,y)\). The second shows the system response in the \((t,x)\) over the time interval of \(0\leq t\leq 50\). The initial conditions are \(x_{0}=2\), \(y_{0}=0\), \(t_{0}=0\)
