So, I am trying to define the equation phi_E, then I have to differentiate this equation to find the equations I am looking for. A stands for alpha and B stands for Beta, they are constants in the equation. There seems to be a problem with phi_E
syms A B x phi_E = [(A.*x(1-x))./(x + B.*(1-x))] + [(A.*x(1-x))./((1-x) + B.*x)]; phi_E1= phi_E + (1-x)*diff(phi_E,x) ...
