The solution

You have entered [src]
x_2*cos(3*x)
$$x_{2} \cos{\left(3 x \right)}$$
x_2*cos(3*x)
Detail solution
  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 answer is:

The first derivative [src]
cos(3*x)
$$\cos{\left(3 x \right)}$$
The second derivative [src]
0
$$0$$
The third derivative [src]
0
$$0$$
