$$\frac{e^{x}}{e^{x} - 1}$$

E^x/(E^x - 1)

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = e^{x}$ and $g{\left(x \right)} = e^{x} - 1$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. The derivative of $e^{x}$ is itself.
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $e^{x} - 1$ term by term:
  1. The derivative of the constant $-1$ is zero.
  2. The derivative of $e^{x}$ is itself.
  The result is: $e^{x}$
Now plug in to the quotient rule:

$\frac{\left(e^{x} - 1\right) e^{x} - e^{2 x}}{\left(e^{x} - 1\right)^{2}}$
Now simplify:

$- \frac{1}{4 \sinh^{2}{\left(\frac{x}{2} \right)}}$

The answer is:

$- \frac{1}{4 \sinh^{2}{\left(\frac{x}{2} \right)}}$
