When writting in mathematical expression, h(t) = 𝛿(t-0.02). I expect the impulse signal to shift right by 0.02 seconds after plotting it.
Why do I receive 'Error using sym>tomupad' in Line 6 when plotting impulse signal with right time shifting?

%create symbolic functions x, a, b, c, d, e, f_c with independent variable t
syms x(t) a(t) h(t) b(t) c(t) d(t) e(t) f_c(t)
x(t) = cos(100*pi*t);
a(t) = x(0.4*t);
h(t) = stem([0]+0.02,[1]);
%plot signal x(t)
