The spruce budworm is one of the most damaging native insects affecting spruces and true fir in Canada. A model for the budworm population dynamics is given by the following differential equation: Ludwig et al (1978) BN2 dt In which, r_B and K_B represent the growth rate and carrying capacity respectively, and A and B are positive constansts 1 Using odeint function (already imported at the top of this notebook), numerically solve this differential equation us ing a time interval of e
