Question

if u=f(x,y)=c,then dy\dx is equal to​

Answer 1

Answer:

if u=f(x,y)=c,then dy\dx is equal to 4xy square

Answer 2

Given :

COnsider the given that u = f(x, y) = c

Find:

Differentiation of the fucntion

Solution:

we know that the derivative of the constant function is zero therefore

$\frac{du}{dx}=0$
