I am new in Mathematica.When I try to sketch a phase portrait for the nonlinear system, I don't know how to plan the input values for the ODEs to get the right FIGURE.
My example is from a book as follows:
Would you like to tell me why we choose the input values for the ODEs such as ode1[0.1,0.16]; ode1[0.1,-0.06];...? You see, when I tried to change the values ,I can't see the figure any more.
