Question

Suppose that f(x) = x 3 − 3xy2 represents velocity potential function of certain fluid flow. Find the linear approximation of the function at the point (1, 2).​

Answer 1

Step-by-step explanation:

Suppose that f(x) = x 3 − 3xy2 represents velocity potential function of certain fluid flow. Find the linear approximation of the function at the point (1, 2)

f(x)=X³-3XY²

f(1,2)= (1)³-3(1)(2)²

=1-3×4

= -11.
