Transform

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = \sin{\left(x \right)}$ and $g{\left(x \right)} = 3 - 2 \cos{\left(x \right)}$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. The derivative of sine is cosine:
  
  $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $3 - 2 \cos{\left(x \right)}$ term by term:
  1. The derivative of the constant $3$ is zero.
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. The derivative of cosine is negative sine:
      
      $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
    So, the result is: $2 \sin{\left(x \right)}$
  The result is: $2 \sin{\left(x \right)}$
Now plug in to the quotient rule:

$\frac{\left(3 - 2 \cos{\left(x \right)}\right) \cos{\left(x \right)} - 2 \sin^{2}{\left(x \right)}}{\left(3 - 2 \cos{\left(x \right)}\right)^{2}}$
Now simplify:

$\frac{3 \cos{\left(x \right)} - 2}{\left(2 \cos{\left(x \right)} - 3\right)^{2}}$

The answer is:

$\frac{3 \cos{\left(x \right)} - 2}{\left(2 \cos{\left(x \right)} - 3\right)^{2}}$
