    Population Modelling Homework: Immigration, Growth & Recovery

    So what I've done is, I've found the value of M using the quadratic formula, this is in terms of S. Is this all I have to do? It feels inadequate...not that I'm undermining your way of thinking... I probably stopped short... so if i directly integrate M'= -M^2 + SM + I, which will presumably...

    Eigenvalues with a leslie population model

    Homework Statement In the Leslie population model, suppose matrix A has a strictly dominant eigenvalue \lambda_1. Age class evolution is given by: x^{(k)} = Ax^{(k-1)}; initial population is x^{(0)}. (i) Initially, let x^{(0)} be the linear combination a_1x_1 + a_2x_2 + ... + a_nx_n, of A's...

    Area of a parallelogram using determinants

    yes... But how is that relevant to your question... i said find the two new vectors and then cross multiply the two new vectors he he... not multiply or cross-multiply the individual vectors he he... And if I wasn't clear let me rephrase. -------------------- 1st step: find the two new...

    Area of a parallelogram using determinants

    technically there is a 3rd vector which could be r = (0,0,0) and NEVER ignore any component given in a question like this :P So, let the origin = r therefore find the vectors rv and ru Then, find the magnitude of the cross product of the two vectors, rv and ru i.e. |rv x ru| Your answer...

    Population Modelling Homework: Immigration, Growth & Recovery

    Homework Statement "The very simple population model for a resource limited population with constant immigration, and no breeding, M'(t) = M(S-M) + I attempts to describe the growth of corals on a reef. Function M(t) represents the biomass of corals." a - Explain which term gives the...
