Question

Suppose that the directional derivatives of f sx, yd are known at a given point in two nonparallel directions given by unit vectors u and v. Is it possible to find =f at this point? If so, how would you do it?

Answer 1

Answer:

Step-by-step explanation:

Application of vector notation comes into play here, by using the directional derivatives of f(x,y) at a given point in two non - parallel directions which are given by their respective units u and v, also for both Duf and Dvf are given.

The detailed analysis is carefully shown step by step in the attachment.
