$f (x) = 6 x e^{x} \csc (x)$

Step 1

Since $6$ is constant with respect to $x$ , the derivative of $6 x e^{x} \csc (x)$ with respect to $x$ is $6 \frac{d}{d x} [x e^{x} \csc (x)]$ .

$6 \frac{d}{d x} [x e^{x} \csc (x)]$

Step 2

Differentiate using the Product Rule which states that $\frac{d}{d x} [f (x) g (x)]$ is $f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where $f (x) = x e^{x}$ and $g (x) = \csc (x)$ .

$6 (x e^{x} \frac{d}{d x} [\csc (x)] + \csc (x) \frac{d}{d x} [x e^{x}])$

Step 3

The derivative of $\csc (x)$ with respect to $x$ is $- \csc (x) \cot (x)$ .

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) \frac{d}{d x} [x e^{x}])$

Step 4

Differentiate using the Product Rule which states that $\frac{d}{d x} [f (x) g (x)]$ is $f (x) \frac{d}{d x} [g (x)] + g (x) \frac{d}{d x} [f (x)]$ where $f (x) = x$ and $g (x) = e^{x}$ .

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) (x \frac{d}{d x} [e^{x}] + e^{x} \frac{d}{d x} [x]))$

Step 5

Differentiate using the Exponential Rule which states that $\frac{d}{d x} [a^{x}]$ is $a^{x} \ln (a)$ where $a$ = $e$ .

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) (x e^{x} + e^{x} \frac{d}{d x} [x]))$

Step 6

Step 6.1

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

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) (x e^{x} + e^{x} \cdot 1))$

Step 6.2

Multiply $e^{x}$ by $1$ .

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) (x e^{x} + e^{x}))$

Step 7.1

Apply the distributive property.

$6 (x e^{x} (- \csc (x) \cot (x)) + \csc (x) (x e^{x}) + \csc (x) e^{x})$

Step 7.2

Apply the distributive property.

$6 (x e^{x} (- \csc (x) \cot (x))) + 6 (\csc (x) (x e^{x})) + 6 (\csc (x) e^{x})$

Step 7.3

Multiply $- 1$ by $6$ .

$- 6 x e^{x} (\csc (x) \cot (x)) + 6 \csc (x) (x e^{x}) + 6 \csc (x) e^{x}$

Step 7.4

Reorder terms.

$- 6 e^{x} x \cot (x) \csc (x) + 6 e^{x} x \csc (x) + 6 e^{x} \csc (x)$
