The motion of a damped harmonic oscillator is given by d +B= x(t)+kx(t) = 0. dt d²x(t) dt² We restrict the damping parameter ß to be strictly positive, so p > 0. Write the 2nd order ODE as a first order system and classify the fixed point for all possible values of ß and k. Determine the portions of (B,k) where the trivial equilibrium is a node, spiral, etc.

can you provide explanations 

The motion of a damped harmonic oscillator is given by
d
+B=x (t) +kx(t) = 0.
dt
d²x(t)
dt²
We restrict the damping parameter ß to be strictly positive, so ß > 0. Write the 2nd order
ODE as a first order system and classify the fixed point for all possible values of ß and
k. Determine the portions of (P, k) where the trivial equilibrium is a node, spiral, etc.
