4*sin (t)

$$4 \sin^{2}{\left(t \right)}$$

4*sin(t)^2

Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = \sin{\left(t \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d t} \sin{\left(t \right)}$ :
  1. The derivative of sine is cosine:
    
    $\frac{d}{d t} \sin{\left(t \right)} = \cos{\left(t \right)}$
  The result of the chain rule is:
  
  $2 \sin{\left(t \right)} \cos{\left(t \right)}$
So, the result is: $8 \sin{\left(t \right)} \cos{\left(t \right)}$
Now simplify:

$4 \sin{\left(2 t \right)}$

The answer is:

$4 \sin{\left(2 t \right)}$
