I have the differential equation:
I have to find the equilibria and solve them.
Second I have to answer the question:
Let x1(t) be its particular solution such that x1(t1)=-7 - for some time instant t1. Is it possible that x1(t)=2 for some t? Explain.
To be honest, I have no clue about how to answer to the second question...
I find the points by setting:
x=-6 or x=1
to get the equilibrium points:
= 17 for x=-6 and 7 for x=1
so both points are unstable.
Is this true? - How can I answer the second question.
Another quick question:
Is the differential equation linear? Is it separable?
No it's not linear because it contains the second power of x. It's not separable, because it can not be written as dx/h(x)=t*g(t)
Is this the right answer?
