I have the following codes

delta=[-2*pi:0.063:2*pi];
y=sin(delta);
subplot(3,2,1)
plot(y)
y=cos(delta);
subplot(3,2,2)
plot(y)
title(sin(delta))

My question is how do i put the title for each graph and labels? i tried to to do title(sin(delta)) but it doesn't show

Starting in R2019b, you can use the tiledlayout and nexttile functions to create a configurable tiling of plots. The configuration options include:

Control over the spacing between the plots and around the edges of the layout
An option for a shared title at the top of the layout
Options for shared x- and y-axis labels
An option to control whether the tiling has a fixed size or variable size that can reflow

For more information, see Combine Multiple Plots.

For R2019a and before, put the title commands after the plot and before the next subplot. Specify the title as a character vector or string scalar.

delta=[-2*pi:0.063:2*pi];
y=sin(delta);
subplot(3,2,1)
plot(y)
title('sin(delta)')  
 
y=cos(delta);
subplot(3,2,2)
plot(y)
title('cos(delta)')

For subplots I often prefer to use ntitle rather than title. The difference is ntitle keeps the text closer to the data, whereas title places the text high above the axes, where it may appear to be an xlabel for to the plot above.
