Detail solution
  1. Apply the product rule:

    ; to find :

    1. Apply the power rule: goes to

    ; to find :

    1. Let .

    2. The derivative of sine is cosine:

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

      1. Differentiate term by term:

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

          So, the result is:

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
                      2             
2*x*sin(5*x - 3) + 5*x *cos(5*x - 3)
$$5 x^{2} \cos{\left(5 x - 3 \right)} + 2 x \sin{\left(5 x - 3 \right)}$$
The second derivative [src]
                      2                                   
2*sin(-3 + 5*x) - 25*x *sin(-3 + 5*x) + 20*x*cos(-3 + 5*x)
$$- 25 x^{2} \sin{\left(5 x - 3 \right)} + 20 x \cos{\left(5 x - 3 \right)} + 2 \sin{\left(5 x - 3 \right)}$$
The third derivative [src]
  /                                           2              \
5*\6*cos(-3 + 5*x) - 30*x*sin(-3 + 5*x) - 25*x *cos(-3 + 5*x)/
$$5 \left(- 25 x^{2} \cos{\left(5 x - 3 \right)} - 30 x \sin{\left(5 x - 3 \right)} + 6 \cos{\left(5 x - 3 \right)}\right)$$
