Consider the spring model

x''−3x+3(x^3)=0
where the linear part of the spring is repulsive rather than attractive (for a normal spring it is attractive). Rewrite this as a system of first-order equations in x and y=x.
x' =
y' =

I am thinking that there is a typo...
are you sure it says rewrite as $$y=x$$?

anonymous · Answer

y=x'

anonymous · Answer

and we should find out (x,y)=(x,x')=state space vector.
