| Abstract: |
| Using the theories of polarity and the properties
of cubic curves on Newton's classification. The relationships of the standard equations
with the coordinate system, and also, every kind of cubic curves' standard equations were
developted. |
| Key words: cubic curves,Newton's classification,theories of polarity,coordinate system |
