Theory like coordinate geometry

  1. Jan 23, 2008 #1
    is one -one correspondence must for a theory like coordinate geometry , polar coordinate ,vector analysis etc
    to work , i.e theories which work by representing a quantity by a different set of quantities
    behaving alike

    It's hard to tell exactly what you're asking... but I think I can answer.

    It is fairly common to allow many different notations for the same object; you just have to include rules for identifying when two notations denote the same object.

    e.g. 1/2 and 2/4 are two different notations for the same rational number, and 0° and 360° are two different notations for the same angle. (0° and 360° are different angular displacements, of course)

    what i meant was like in vector we represent a vector by a straight directed line and then use its property to find the property of the represented vector .

    this is because they belong to same class of entities i.e vectors

    similiarly ordered triplets and points are two quantities which represent each other in space
