I am trying to plot (E_2/E_m) vs V_f which I have denoted (E_2/E_m) as y_1 in my code. The range for V_f should be from 0 to 1. Can someone please help me with plotting the symoblic constant V_f vs (E_2/E_m), it would be greatly appreciated. Attatched is im age of my code and my code underneith it.
E_2f = 14.8;
E_m = 3.45;
v_m = 0.36
%Vm = 1 - Vf
syms V_f
E_2 = ((E_2f)*(E_m))./((V_f)*(E_m)+(1-V_f)*(E_2f));
y_1 = E_2/E_m;
figure(1);
hold on;

Try this:
figure(1)
fplot(y_1, [1E-3 1E+3])
grid
The rest of the code is unchanged.
