Can We Change the Origin in the xy Plane?

LagrangeEuler · Mar 15, 2015

Almost always in xy plane we take that origin is ##(0,0)##. Is it possible to take that origin is in the point ##(1,1)##, or some other point?

The point (0,0) is called origin. That is just a definition. It does not make sense to give another point the same name.

If I want to use some translation in x-axis I need more then one coordinate system, for example. So origin of first system for instance is ##(0,0)## and for second is ##(2,0)##?

DrewD · Mar 15, 2015

The origin of the second system is at ##(2,0)## in the coordinates of the first system, but using the coordinates of the second system the origin, by definition, is at ##(0,0)##. As mfb said, it doesn't make sense to use the term to apply to some other point in the coordinate system.
