Divide 384 by 12 then multiply it by 5 to give you 160
Six hundred seventy-two thousandths <0.8
Not sure about this but, is it a line?
Answer: look at the picture
Step-by-step explanation: Hope this help :D

Let

The curl is

where
denotes the partial derivative operator with respect to
. Recall that



and that for any two vectors
and
,
, and
.
The cross product reduces to

When you compute the partial derivatives, you'll find that all the components reduce to 0 and

which means
is indeed conservative and we can find
.
Integrate both sides of

with respect to
and

Differentiate both sides with respect to
and




Now

and differentiating with respect to
gives




for some constant
. So
