$\sin (x^{5})$

Step 1

Differentiate using the chain rule, which states that $\frac{d}{d x} [f (g (x))]$ is $f' (g (x)) g' (x)$ where $f (x) = \sin (x)$ and $g (x) = x^{5}$ .

Step 1.1

To apply the Chain Rule, set $u$ as $x^{5}$ .

$\frac{d}{d u} [\sin (u)] \frac{d}{d x} [x^{5}]$

Step 1.2

The derivative of $\sin (u)$ with respect to $u$ is $\cos (u)$ .

$\cos (u) \frac{d}{d x} [x^{5}]$

Step 1.3

Replace all occurrences of $u$ with $x^{5}$ .

$\cos (x^{5}) \frac{d}{d x} [x^{5}]$

Step 2

Differentiate using the Power Rule.

Step 2.1

Differentiate using the Power Rule which states that $\frac{d}{d x} [x^{n}]$ is $n x^{n - 1}$ where $n = 5$ .

$\cos (x^{5}) (5 x^{4})$

Step 2.2

Reorder the factors of $\cos (x^{5}) (5 x^{4})$ .

$5 x^{4} \cos (x^{5})$
