Im having some trouble wiht this problem, i was wondering if any one could help?
there are three equations
u = [0.25*S]/[S+0.005]
dS/dt = -0.42uX
dX/dt = uX
with the initial conditions at to, xo = 2, s0 = 63.6
I set up the Mfile for u, but i have no idea how to set up the differentials so that i get a plot of change in S and X onver time.
Can anyone please help?
