I often see people cramming about learning the position of points in a 3D Co-ordinate system. So, Here I have a conjecture.
Imagine the Points (3,-3,-3).
First, Using Basic Co-ordinate system geometry, We can see that (3,-3) lies in the 4rd Quadrant. Now, Since (-3) is a negative number, The point (3,-3,-3) will lie in the octate just behind The 4rd Quadrant i.e. The 8th Octnt
Similarly, For any point \((a,b,c)\) We can first visualize The quadrant in which \((a,b)\) lies, and then visualize the octant in which \((a,b,c)\) lies, using the value of c(whether it is positive or negative.)
