Can We Change the Origin in the xy Plane?

In summary, the origin in a coordinate system is typically denoted as (0,0) in the xy plane. It is not logical to give the same name to another point in the system. When using multiple coordinate systems, the origin of each system is defined differently, but it would not make sense to refer to a different point as the origin within the same system.

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)##?
 
  • #4
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.
 

FAQ: Can We Change the Origin in the xy Plane?

Can we change the origin in the xy plane?

Yes, it is possible to change the origin in the xy plane. This can be done by translating the coordinate system to a new location. However, it is important to note that this does not change the actual coordinates of the points on the plane, but rather the reference point from which they are measured.

What is the purpose of changing the origin in the xy plane?

The purpose of changing the origin in the xy plane is to make calculations and measurements easier. By shifting the origin to a more convenient location, the coordinates of points can be simplified and graphing equations can be made simpler.

How is the origin changed in the xy plane?

The origin in the xy plane is changed by translating the coordinate system. This is done by adding or subtracting a certain amount to the x and y coordinates of all points on the plane. For example, if the new origin is (2,3), then all points on the plane will have 2 added to their x-coordinate and 3 added to their y-coordinate.

Are there any limitations to changing the origin in the xy plane?

Yes, there are limitations to changing the origin in the xy plane. The new origin must still lie on the plane and cannot be outside of its boundaries. Additionally, changing the origin may alter the appearance of the graph and distort the proportions of the axes.

How does changing the origin affect the equation of a line in the xy plane?

Changing the origin in the xy plane does not affect the equation of a line. The slope and y-intercept of the line will remain the same, but the coordinates of the points on the line will change. This is because the equation of a line is independent of the origin and is solely determined by the slope and y-intercept.
