I learned in high school that a quadrant is one quarter of an Euclidean plane. I looked up definitions on the web and the term may also refer to a 90° arc lengh of a circle.

But in the case of Rindler coordinates, considering only 1 space dimension, its clear that they cover only a part of Minkowski space that is bounded by two 45° lines, and this is not in agreement with the definitions of a quadrant.

On the other hand, I have so little knowledge about Relativity, so is this term used differently in Relativity?
