a) Build the model in Tellurium and run a simulation. Compute the Jacobian at steady
state using the method getFull Jacobian(). Make sure you are at steady state!
b) Write out the values for n and p
c) Write out the differential equations.
d) Write out the state space representation in terms of the rate constants etc.
e) Compute the values in the Jacobian matrix from d) by substituting the values of the rate
constants etc and any data you need from the simulation.
f) Confirm that the Jacobian you get in e) is the same as the one computed from the
simulation in a).
g) Is the system stable or not? If you find an eigenvalue of zero, that means the system is
marginally stable. You can get the eigenvalues using the tellurium method r.getFullEigenvalues()
