Determine the octant(s) in which (x,y,z) is located so that the conditions are satisfied.

x > 0, y < 0, z > 0

I just had to look up octants myself.  They are not that difficult

With 2 dimensions you have quadrants.

With 3 dimensions you have octants becasue you also have to consider whether y is positive or negative.

The first four octants are the same as above only z must be positive

the next four (5,6,7,8) are also the same as above but z is negative.

Here is an artical on it.

So lets look at your problem

Determine the octant(s) in which (x,y,z) is located so that the conditions are satisfied.

x > 0, y < 0, z > 0

z is positive so that makes it 1,2,3 or 4

x is positive that makes it 1 or 4 (just think in 2D for this)

y is negative sio it must be  4

So it is octant 4

If you give me feeedback I will be more likely to help you in the future.

It would be even better if you join up and then we can all get to know you.

I give members answer priority - I think most others do too :)

Thank you so much for helping me. I just joined as you suggested :)
