I will have to check the spreadsheet and the web page. Other than that, I think the other errors are from rounding. > Red x-comp = b cos(-48) = -18.55 (you got -18.9) > Red y-comp = b sin(-48) = -20.61 (you got -20.3021) > > I checked all cos and sin formulas in the drawing and all seem to be OK, the > only things that are wrong are the final decimal numbers. I will check that and get back to you.
