I'm trying to write in a derivative of f(t)= (1)/(55) (20π sin((1)/(11) π t) + 33ℯ^(-((3)/(10)) t) sin(2π t) - 220π ℯ^(-((3)/(10)) t) cos(2π t))
here's what I'm writting in:
Td=1/55*(20*pi*sin(1/11*pi*t)+33*exp(-3/10*t).*sin(2*pi*t)-220*pi*exp(-3/10*t).*cos(2*pi*t)) t;

You seem to have a rogue t at the end of your expression. If you get rid of that, then ...
Td=1/55*(20*pi*sin(1/11*pi*t)+33*exp(-3/10*t).*sin(2*pi*t)-220*pi*exp(-3/10*t).*cos(2*pi*t));
Note that in the MATLAB editor, a red squiggly line appeared under that t, indicating the syntax error.
