Detail solution

Differentiate $a \sin^{2}{\left(x \right)} + 1$ term by term:
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Let $u = \sin{\left(x \right)}$ .
  2. Apply the power rule: $u^{2}$ goes to $2 u$
  3. 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:
    
    $2 \sin{\left(x \right)} \cos{\left(x \right)}$
  So, the result is: $2 a \sin{\left(x \right)} \cos{\left(x \right)}$
2. The derivative of the constant $1$ is zero.
The result is: $2 a \sin{\left(x \right)} \cos{\left(x \right)}$
Now simplify:

$a \sin{\left(2 x \right)}$

The answer is:

$a \sin{\left(2 x \right)}$
