hlep me please, math question, divF and curlF?

Question

how to find the divF and curlF for F(x,y,z)= ln x i+e^(xyz) j+tan^(-1)(z/x) k

i am stick at the derivvative e^(xyz) and tan^(-1)(z/x)

Answer 1

The partial derivatives you need are as follows.
d(e^(xyz))/dx = yze^(xyz), d-/dy = xze^(xyz), and
d-/dz = xye^(xyz).

d(arctan(z/x)/dx = [1/(1 + (z/x)^2)]*(-z/x^2), d-/dy = 0, and
d-/dz = [1/(1 + (z/x)^2)]*(1/x).
