How to plot symbolic function ?

Hello,

So I have a function f of a symbolic variable let's say x , and I would like to plot my function versus 1/x.

How can I do that ?

This is an example of my code, I'd like to plot E_norm versu 1/b.

syms b ; % 1/T  

syms N ; 

Z = 2*(2*cosh(b))^N ; 
F = log(Z)/N;
E_norm = -diff(F,b);

E_norm = simplify(E_norm) ; 
fplot(E_norm,[ 0 6])

Not sure exactly what you want.

syms b ; % 1/T  
syms N ; 
Z = 2*(2*cosh(b))^N ; 
F = log(Z)/N;
E_norm = -diff(F,b);
E_norm = simplify(E_norm) ; 
fplot(E_norm,[ .1, 6]);
hold on
fplot(1/b,[.1,6]);
