4*(sin(t) - t*cos(t))
Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Differentiate term by term:

      1. The derivative of sine is cosine:

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

        1. Apply the product rule:

          ; to find :

          1. Apply the power rule: goes to

          ; to find :

          1. The derivative of cosine is negative sine:

          The result is:

        So, the result is:

      The result is:

    So, the result is:


The answer is:

The graph
The first derivative [src]
4*t*sin(t)
$$4 t \sin{\left(t \right)}$$
The second derivative [src]
4*(t*cos(t) + sin(t))
$$4 \left(t \cos{\left(t \right)} + \sin{\left(t \right)}\right)$$
The third derivative [src]
4*(2*cos(t) - t*sin(t))
$$4 \left(- t \sin{\left(t \right)} + 2 \cos{\left(t \right)}\right)$$
