Answer:
C. 8√3/3
Step-by-step explanation:
It can be useful to remember that the ratio of sides in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is the short leg is 1/√3 times the length of the longer leg.
8(1/√3) = 8(√3/3) . . . . . matches choice C
Answer:
2
Step-by-step explanation:
We're looking for
such that
, which requires



Integrating both sides of the first PDE wrt
gives

Differenting this wrt
gives


but we're assuming
is a function that doesn't depend on
, which is contradicted by this result, and so there is no such
and
is not conservative.
