Creating a Vector Table

I need to create a table of x and corresponding y values (if y=sin(x)). I would like my x column to be 0, 0.2, 0.4, and 0.6 and want corresponding y values to plot in the columns next to it. I would like a y column for the forward difference, backward difference, central difference, and perfect (perfect being y=cos(x)). Thank you in advance for the help!

I'm just unsure as to where to start. I know I'll need to throw in some if/while loops, but I'm not sure where. I'm fairly new to coding, so all of this is a little confusing to me.
