![Find the directional derivative of the function at the given point in the direction of the
vector v:
(a) f(x,y) =
x2+y2
at (1, 2), where v =
(b) g(s, t) = s?e-t at (3,0), where v = (3, 4)
(c) f(x,y, z) = x²y + y?z at (1, 2, 3), where v = (2, –1, 2)
+ Zesty, but ONLY
because this is a function
of three variables instead
of two. The process is
EXACTLY the same.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F78b614ed-f23b-4c4b-945f-0e40ced49f9e%2Fbc9800ff-3fe5-449d-8fdd-8c83b64d8f9c%2Fafsrwy2_processed.png&w=3840&q=75)
