if f(x,y)=c then dy/dx is​

Answer 1

I don't know?

what it's answer

Answer 2

dy/dx = 0

Derivatives:

According to the differentiation rule the derivative of a constant is always zero. Since, a constant number is a horizontal line or a slope, hence the rate of change will be zero and thus the differentiation of a constant is always zero.

In the given question a function is given which is equal to a constant and we have to find its derivative.

$\frac{dy}{dx} {f(x,y)$

$\frac{dy}{dx} (c)$ = 0
