For the life of me i can't get this to work Very simple
I want to say the following
RC = [0: 50,000];
RE = [ 0 : 50,000];
%Two vectors for the function
% here is my function
400 = RC/(10050 + 2*RE)
I want to see a plot that shows me all the ratios of RC and RE that satifiy the equation with in the %specified range of RC and RE
Please Help

A little algebra rearranges it to a simple linear equation:
RE = linspace(0, 50000, 500);
% Two vectors for the function
% here is my function:
% 400 = RC/(10050 + 2*RE)
RC = 400 .* (10050 + 2*RE);
figure(1)
plot(RE, RC)
grid
xlabel('RE')
ylabel('RC')
