# Grad of a function in vector notation

1. The problem statement, all variables and given/known data

q = xy$$^{2}$$z i + y$$^{2}$$xz j + e$$^{2z}$$ k

2. Relevant equations

Grad (f) = (fx,fy,fz), where fx, fy, fz are partial derivatives

3. The attempt at a solution

I am Comptent at computing the gradient of a function, however i do not see how to do this when in vector notation. Any Help would be greatly appreciated!

Thank You

Hi leoflindall!

(have a del: ∇ and try using the X2 tag just above the Reply box )
We have gradient of scalars, not of vectors.

Are you sure it isn't .q, the divergence of q ?

Of course i did, i tihnk it must be the late hour but i was just being silly! Thank you for your help!
