Find the directional derivative of at the point (1, 3) in the direction toward the point (3, 1). g

Complete Question:

Find the directional derivative of g(x,y) = at the point (1, 3) in the direction toward the point (3, 1)

Directional derivative at point (1,3),  

Step-by-step explanation:

Get and at the point (1, 3)

g(x,y) =

Let P =  (1, 3) and Q = (3, 1)

Find the unit vector of PQ,

The unit vector is therefore:

The directional derivative of g is given by the equation:

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
