with(DEtools); with(plots); with(plots, implicitplot);

LC := [diff(x(t), t) = x(t)*(1-x(t)^2-y(t)^2)+y(t)*((1-x(t))^2+y(t)^2), diff(y(t), t) = y(t)*(1-x(t)^2-y(t)^2)-y(t)*((1-x(t))^2+y(t)^2)]

p1 := DEplot(LC, {x(t), y(t)}, t = 0 .. 100, [x(0) = 1, y(0) = 1])

Error, (in DEtools/DEplot/CheckInitial) too few initial conditions: [x(0) = 1]
