hi,thank u for all your helps,,could anybody help me with drawing S(t)=sin(2pift)+1/2sin(6pift) in matlab but each graph as individual like sin(2pift)as on gragh then 1/2sin(6pift) as theother graph and at the end S(t) that is sum of two graph .((assume that T=1 sec)) many many tanksssssssssssssssssssssssss

Assuming you want all 3 curves on a single plot:
f = 0.5; % Set f to whatever it's supposed to be here
S1 = @(t) sin(2*pi*f*t);
S2 = @(t) 1/2 * sin(6*pi*f*t);
S = @(t) S1(t) + S2(t);
T = linspace(0,1,1000);
plot(T,S1(T),T,S2(T),T,S(T));
legend({'S1(t)','S2(t)','S(t)'});

Maybe better to avoid anonymous functions (quite hard because of the condensed syntax) in answers to beginners?
