3. The Spruce Budworm is a pest which destroys coniferous trees. Its population (in some instances) is modeled by the differential equation S² S' (t) = 0.55S (1- 555(1-5). 1+S² This is an autonomous differential equation, meaning the right hand side depends only on the value of the dependent variable. So we can find equilibrium solutions by setting the nicht hand ide C levi.

Question

This problem is dealing with the Newtons meathod algorithmn which requires both a function and a derivative of that function. I can do everything involving the algorithmn but I need help with with getting the function S(t).

1+ S²
This is an autonomous differential equation, meaning the right hand side depends only
on the value of the dependent variable. So we can find equilibrium solutions by setting
the right hand side equal to 0 and solving for S.
