Homework Statement
So I am looking at example where stabilty is determined.
And do not understand how linerazation is done.
x'=x+2y-ln(1+x)-siny+x^3
y'=4x+2y-sinx+y^2
Homework Equations
so the system after linearization looks like:
x'=y
y'=3x+2y
So i thought that higher order x and y are eliminated and other functions are just displaced with x and y.
I think it should not be true,could someone help me with this,please?
