It’s either 1. Or 2. I’m really not sure which one tho so sorry! There’s not enough information given but if I had to guesstimate I would say 1.
Half of 135
135/2 = 67.5
half of 135 is 67.5
67.5 is your answer
hope this helps
Answer:
252
Step-by-step explanation:
espero que te ayude :3
, the boundary of
, is a circle in the
plane centered at the origin and with radius 2, hence we can parameterize it by

with
. Then the line integral is



By Stokes' theorem, the line integral of
along
is equal to the surface integral of the curl of
across
:

Parameterize
by

with
and
. Take the normal vector to
to be

The curl is

Then the surface integral is
