Expert Solution
Step 1: Asymptotically stability check
Noted that for given system of non linear differential equations
and given Liapunov function
equilibrium point is said to be asymptotically stable if the following expression
is negative definite,
In other words,
Now noted that
Obviously ,R.H.S term of above ,because inside the braket ,this is sum of square terms ,equal to zero implies each variavle indicate zero.
