Hello! I have trouble with this set:

EX. Consider set of equations:

$\displaystyle x^{,}_{1}= -x_{1}+x^{2}_{2}\\x^{,}_{2}= -x_{2}-x_{1}x_{2}$

a) Show that any saturated answers are defined for all simple.

b) Show that zero solutions are asymptotically stable, when t to ascond + infinity.

c) Is zero solution is stable, when t to ascond -infinity?

(Sorry for my errors)
