Dear Prof Azeem

As per the attached image, Will you consider this Coordinate Geometry

Variation as correct or incorrect ?.

The Four Quadrants Positions are changed along with the positive and negative numbers on the x and y axis.

Awaiting your reply,

Thanks & Regards,

Prashant S Akerkar

Hi Prashant,

This variation in the illustration is a 180-degree rotation of the conventional Cartesian plane. While not strictly incorrect, it may be confusing as it is easier to associate negative numbers with being on the left or bottom. However, in a scenario is which negative values actually indicate a rise in the metric of interest, such a variation can be useful.

Thanks for asking,

Azeem

I welcome your questions on algebra, 2D and 3D geometry, parabolic functions and conic sections, and any other mathematical queries you may have.
