%% Include Loop Variable Value in Graph Title
% Use a loop to create a figure containing four subplots. In each subplot, plot a sine wave with different frequencies based on the loop variable k. Add a title to each subplot that includes the value of k.

x = linspace(0,10,100);
for k = 1:4
    subplot(2,2,k);
    yk = sin(k*x);
    plot(x,yk)
    title(['y = sin(' num2str(k) 'x)'])
end
