Error using plot for symbolic function

Hello,

My code is the following one:

syms g(x) x
t = [0:0.005:4];
wn = 10;
zeta = 2;
g(x) = wn/(sqrt((zeta*zeta)-1)) * exp(-(zeta*wn*x))*sinh(wn*sqrt((zeta*zeta)-1)*x);

plot(t,g(x));

I get the error 'A numeric or double convertible argument is expected'. I can't find what i'm doing wrong...

plot(t, g(t))
