Surface integral - question about "restrictions"

Click For Summary
SUMMARY

The discussion centers on the redundancy of specifying "in front of the yz-plane" when the problem already states "in the first octant," which inherently includes the condition x ≥ 0. Participants agree that the additional restriction is unnecessary, as the first octant definition sufficiently covers the spatial constraints of the problem. This highlights the importance of clarity in mathematical problem statements to avoid confusion.

I am not sure why the question had to say "in front of the yz-plane". If I understand correctly, that means x >= 0. However, isn't this restriction already accounted for by saying "in the first octant" which means x, y, z are all >= 0?

I agree that the problem statement is redundant.
There’s no need to say “in front of the yz-plane” if it already says “in the first octant”.
