Question

For the partial derivatives given in Exercises 55–58, find the

most general form for a function of three variables, $f(x,y,z)$,

with the given partial derivative.

$\frac{\partial f}{\partial x}=0$

Step-by-Step Solution

Answer

 The most general form of $f(x, y, z)$so that $\frac{\partial f}{\partial x}=0$is $f(x, y, z)=h(y, z)$

Step 1: Given information

Given derivative is $\frac{\partial f}{\partial x}=0$

Step 2: The objective is to find the most general form of a function f ( x ,   y ,   z )  

 Suppose $f(x, y, z)=h(y, z)$

$\frac{\partial f}{\partial x}=0$Because $y$and $z$treated as constant.

Hence, the most general form of $f(x, y, z)$so that $\frac{\partial f}{\partial x}=0$is $f(x, y, z)=h(y, z)$
