Detail solution
  1. Differentiate term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Let .

      2. The derivative of sine is cosine:

      3. Then, apply the chain rule. Multiply by :

        1. The derivative of a constant times a function is the constant times the derivative of the function.

          1. Apply the power rule: goes to

          So, the result is:

        The result of the chain rule is:

      So, the result is:

    2. Apply the power rule: goes to

    The result is:


The answer is:

The first derivative [src]
  1                
- -- + 8*t*cos(4*x)
   2               
  x                
$$8 t \cos{\left(4 x \right)} - \frac{1}{x^{2}}$$
The second derivative [src]
  /1                 \
2*|-- - 16*t*sin(4*x)|
  | 3                |
  \x                 /
$$2 \left(- 16 t \sin{\left(4 x \right)} + \frac{1}{x^{3}}\right)$$
The third derivative [src]
   /3                 \
-2*|-- + 64*t*cos(4*x)|
   | 4                |
