  x      sin(x)

$$\frac{1}{\sin{\left(x \right)}} + \frac{\sin{\left(1 \right)}}{x}$$

sin(1)/x + 1/sin(x)

Detail solution

Differentiate $\frac{1}{\sin{\left(x \right)}} + \frac{\sin{\left(1 \right)}}{x}$ term by term:
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $\frac{1}{x}$ goes to $- \frac{1}{x^{2}}$
  So, the result is: $- \frac{\sin{\left(1 \right)}}{x^{2}}$
2. Let $u = \sin{\left(x \right)}$ .
3. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
4. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(x \right)}$ :
  1. The derivative of sine is cosine:
    
    $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
  The result of the chain rule is:
  
  $- \frac{\cos{\left(x \right)}}{\sin^{2}{\left(x \right)}}$
The result is: $- \frac{\cos{\left(x \right)}}{\sin^{2}{\left(x \right)}} - \frac{\sin{\left(1 \right)}}{x^{2}}$

The answer is:

$- \frac{\cos{\left(x \right)}}{\sin^{2}{\left(x \right)}} - \frac{\sin{\left(1 \right)}}{x^{2}}$
