How do I form a product of two arrays and add the numerical value of the integral in the plot?

xDataA = linspace(0,4*pi,1024);
yDataA = cos(xDataA);

xDataB = linspace(0,4*pi,1024);
yDataB = cos(xDataB);

I have two arrays here and I want to plot the product and add the numerical value of the integral in the plot.

xData = linspace(0,4*pi,1024);
yDataA = cos(xData);
yDataB = cos(xData);
p = yDataA.*yDataB ;
plot(xData,p)
