The graph:

from to

Piecewise:

The solution

You have entered [src]
x*cos(E)*c*x
$$x c x \cos{\left(e \right)}$$
((x*cos(E))*c)*x
Detail solution
  1. Apply the product rule:

    ; to find :

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

      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:

      So, the result is:

    ; to find :

    1. Apply the power rule: goes to

    The result is:

  2. Now simplify:


The answer is:

The first derivative [src]
x*cos(E)*c + c*x*cos(E)
$$c x \cos{\left(e \right)} + c x \cos{\left(e \right)}$$
The second derivative [src]
2*c*cos(E)
$$2 c \cos{\left(e \right)}$$
The third derivative [src]
0
$$0$$
