(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to find the unit normal vector to x^{2}+z^{2}=16. I can find the unit normal vector to every shape but a cylinder, and I can't seem to see how to do it.

2. Relevant equations

[tex]\nabla[/tex]F=F_{x}i+F_{y}j+F_{z}k

3. The attempt at a solution

I know that I need to find the gradient of the surface equation. I've considered that this gradient may be i-2x-2z. Or am I completely wrong?

If you need more information please say what. Thank you!
