(Strogatz 2.4.1-6) In this question, we will consider the ODE
x^(?)(t)=f(x(t)),
for various choices of right-hand side
f
. Find the fixed points. Classify the linear stability of the fixed points. If linear stability analysis fails, use a graphical argument to determine the stability. Do the above tasks for the following choices of
f
. (a)
f(x)=x(1-x)
(b)
f(x)=x(1-x)(2-x)
(c)
f(x)=tanx
(d)
f(x)=x^(2)(6-x)
(e)
f(x)=1-e^(x^(2))
(f)
f(x)=1-e^(-x^(2))
(g)
f(x)=logx
