For some reason, when I run this MATLAB code, I'm getting what looks like about 10,000 for Rf for the largest Vo on the graph, but MATLAB is giving me Rf at (Vo)max as 100,001

Any ideas?

clc;

clear;

close all;

syms Rf

Rf = 0:0.1:100000;

VRt25 = 18.*(10000)./(10000 + Rf);

VRf25 = 18.*(Rf)./(10000 + Rf);

VRt2505 = 18.*(9977.81)./(9977.81 + Rf);

VRf2505 = 18.*(Rf)./(9977.81 + Rf);

V_difference25 = abs(VRt25 - VRf25);

V_difference2505 = abs(VRt2505 - VRf2505);

Vo_difference = abs(V_difference25 - V_difference2505);

figure;

plot(Rf,Vo_difference)

title('Voltage Difference Vo vs. Rf')

ylabel('Vo Difference [V]')

xlabel('Rf [ohms]')

hold on

%Maximum Vo Difference

[Vo_difference_max,Rf] = max(Vo_difference)
