x \sin (x)

$x \sin (x)$

Step 1

Differentiate using the Product Rule which states that

\frac{d}{d x} [f (x) g (x)]

$\frac{d}{d x} [f (x) g (x)]$ is

f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]

$f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where

f (x) = x

$f (x) = x$ and

g (x) = \sin (x)

$g (x) = \sin (x)$ .

x \frac{d}{d x} [\sin (x)] + \sin (x) \frac{d}{d x} [x]

$x \frac{d}{d x} [\sin (x)] + \sin (x) \frac{d}{d x} [x]$

Step 2

The derivative of

\sin (x)

$\sin (x)$ with respect to

x

$x$ is

\cos (x)

$\cos (x)$ .

x \cos (x) + \sin (x) \frac{d}{d x} [x]

$x \cos (x) + \sin (x) \frac{d}{d x} [x]$

Step 3

Differentiate using the Power Rule.

Step 3.1

Differentiate using the Power Rule which states that

\frac{d}{d x} [x^{n}]

$\frac{d}{d x} [x^{n}]$ is

n x^{n - 1}

$n x^{n - 1}$ where

n = 1

$n = 1$ .

x \cos (x) + \sin (x) \cdot 1

$x \cos (x) + \sin (x) \cdot 1$

Step 3.2

Multiply

\sin (x)

$\sin (x)$ by

1

$1$ .

x \cos (x) + \sin (x)

$x \cos (x) + \sin (x)$

x \cos (x) + \sin (x)

$x \cos (x) + \sin (x)$

x \sin (x)

$x \sin (x)$
