Abscissa and ordinate Abscissa and ordinate In mathematics, the abscissa (; plural "abscissae" or "abscissæ" or "abscissas") and the ordinate are respectively the first and second coordinate of a point in a coordinate system. The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative; after: positive). The ordinate of a point is the signed measure of its projection on the secondary axis, whose absolute value
Bit-paired keyboard but bit-paired keyboards have (rows 10, 11, and 13) instead of and are missing the key, as these are shifted values of digits. This is the complete set of symbols on the Model 33; it is notably missing though these are present on other bit-paired keyboards. On both bit-paired and typewriter-paired keyboards, are paired (rows 11, 12, and 13), but on bit-paired keyboards are paired and is an unpaired key, while on typewriter-paired keyboards and are shifted digits, while are paired and is paired with . In the US, bit-paired keyboards continued to be used into the 1970s, including on
