Homework Statement
I need to find the unit normal vector to x2+z2=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.
Homework Equations
[tex]\nabla[/tex]F=Fxi+Fyj+Fzk
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!
