I have 2 governing equations for my reactions and they are a factor of 4 different variables. How do I use a nested function to solve it.
ds/dt=(d^2s)/dx^2 – ds/dx- s
dq/dt=-∝.s
Subject to below initial & boundary conditions are
t=0,s=0;
x=0,s=1;
x=1,ds/dx=0;
t=0,q=0;
This is part of the bigger set of equations but I'm not sure how to include s, t, q and x in there. All I've worked with before has been everything in terms of changes over time, but here it's time and distance (x). s and q are concentration of two solvents. Beta, gamma and alpha are all constants.
