Question:
Consider {eq}\displaystyle f (x,\ y,\ z) = \dfrac x {y - z} {/eq}. Compute the partial derivative below.
{eq}\displaystyle \dfrac {\partial f} {\partial x}_{(2,\ -1,\ 3)} {/eq}.
Partial Differentiation
While partially differentiating the function {eq}\displaystyle f(x,y,z) {/eq} with respect to {eq}\displaystyle x {/eq}, the variables {eq}\displaystyle y,z {/eq} are considered as constants.
Simply it can be stated that while partially differentiating a function with respect to a particular variable, others are considered as constants.
We need to know that {eq}\displaystyle \frac{d}{dx} x^n = nx^{n-1},\frac{d}{dx} k=0 {/eq} where {eq}\displaystyle k {/eq} is a constant.
