2. Consider x
′ = −(x − y)(1 − x − y) and y
′ = x(2 + y) and plot the solutions. Verify
your qualitative dynamics with MATLAB/Python/fortran.
3. Consider x
′ = x−y
2 and y
′ = y −x
2 and plot the solutions. Verify your qualitative
dynamics with MATLAB/Python/fortran.
4. Consider x
′ = (2 + x)(y − x) and y
′ = (4 − x)(y + x) and plot the solutions. Verify
your qualitative dynamics with MATLAB/Python/fortran.
