From nowon, any set of axes will be lettered only… … Let OX and OY be the original axes, and OX and OY thenew axes meeting at 0, the coordinates of 0 with respect tothe original axes being Xq and yo- Let P be any point in the })lane, its coordinates being x andy with respect to OX and OY, and x and y with respect toOX and OY.
