Answer 1

Step-by-step explanation:

Find the curl for \vec{r}=x^2 yz\vec{i}+(3x+2y)z\vec{j}+21z^2 x\vec{k}.

a) \vec{i}(3x+2y)-\vec{j}(11z^2-x^2 y)+\vec{k}(3z-x^2 z)

b) \vec{i}(x+2y)-\vec{j}(21z^2-x^2 y)+\vec{k}(3z-x^2 z)

c) -\vec{i}(3x+2y)-\vec{j}(21z^2-x^2 y)+\vec{k}(3z-x^2 z)

d) \vec{i}(3x+2y)-\vec{j}(21z^2-x^2 y)+\vec{k}(3z-x^2 z)
