Chapter 12: Q. 57. (page 945)

For the partial derivatives given in Exercises 55鈥�58, find the
most general form for a function of three variables, $f (x, y, z)$ ,
with the given partial derivative.
$\frac{{鈭�}^{2} f}{鈭� x^{2}} = 0$

Short Answer

Expert verified

The most general form of a function $f (x, y, z)$ so that $\frac{{鈭�}^{2} f}{鈭� x^{2}} = 0$ is $f (x, y, z) = x h_{1} (y, z) + h_{2} (y, z)$

Step by step solution

Given information

Given derivative is $\frac{{鈭�}^{2} f}{鈭� x^{2}} = 0$

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

The most general form of a function $f (x, y, z)$ so that $\frac{{鈭�}^{2} f}{鈭� x^{2}} = 0$

Suppose, $f (x, y, z) = x h_{1} (y, z) + h_{2} (y, z)$

Then,

$\frac{d f}{d x} = h_{1} (y, z) + 0 \frac{d^{2} f}{d x^{2}} = 0$

Hence, the most general form of $f$ so that $\frac{{鈭�}^{2} f}{鈭� x^{2}} = 0$ is $f (x, y, z) = x h_{1} (y, z) + h_{2} (y, z)$
