mathematica code in physics

Hello all！！
Does someone use mathematic???
I have a question about Mathematica code -----
""Table[Plot[Sin[x + z] Cos[z], {x, -9, 3Pi}, PlotRange -> {-1, 1}], {z, 0, 2Pi, 0.2}]""
What this code mean ??????
Thanks Thanks

It means it will plot the table values of the function Sin[x + z] Cos[z] in the rectangular window xmin -9, xmax 3Pi, ymin -1, ymax 1. It will plot the default points of x and plot z with the range of 0 to 2Pi in increments of .2
Hope this helps.
