It’s not clear what you intend.
If I interpret your legend correctly, the changed lines may be what you want.
The Code —
t = 1:500;
A = 4;B = 10;C = 2.4; D = 2;
% % g = sin(t/30); %Original Sin Wave
% % g1 = A*g.*(t+B); %1st wave transformation
% % g2 = C*g.*(t*D); %2nd wave transformation
g = @(t) sin(t/30); %Original Sin Wave
g1 = A*g(t+B); %1st wave transformation
g2 = C*g(t*D); %2nd wave transformation
plot(t,g(t),t,g1,t,g2);
legend('g(t) = sin(t/30)', 'g1(t) = Ag(t + B)', 'g2(t) = Cg(Dt)')
title('Wave Transformation'); % percent signs are used to comment code
xlabel('time');
ylabel('value');
My code is a guess so If I got it wrong, experiment to get the result you want.
