Use polar coordinates to find the limit. [if (r, θ) are polar coordinates of the point (x, y) with r ⥠0, note that r â 0+ as
(x, y) â (0, 0).] (if an answer does not exist, enter dne.) lim (x, y)â(0, 0) 7eâx2 â y2 â 7 x2 + y2
1 answer:
I'll take a wild guess and suggest the limit is supposed to be
Converting to polar coordinates, we take
with
and
. This yields
Most important is that the limand is independent of
. Evaluating directly yields
, so we apply L'Hopital's rule:

(3/4) / (1/12)
= (3/4) * 12
= 36/4
= 9
She can create 9
Volume and density because steam is escaping, therefore, less water in the end
Answer:
I think the answer is:
-Y = 4
-Z = 7
-X = 16
-W = 17.46
