Here is the function im dealing with

clear;

syms x(t) X(w)

f1 = 2;

f2 = 3;

x(t) =cos(2*pi*f1*t)

subplot(2,1,1);

ezplot(x);

subplot(2,1,2);

ezplot(x(t-10));

And here are the results

how is this possible, even though there it is a delayed function?

f1 = 2;

f2 = 3;

t=linspace(0,1,1000)

x=cos(2.*pi.*f1.*t)

x1=cos(2.*pi.*f2.*(t-10))

subplot(2,1,1);

plot(t,x);

subplot(2,1,2);

plot(t,x1);
