Detail solution
  1. Let .

  2. The derivative of is itself.

  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:

  4. Now simplify:


The answer is:

The first derivative [src]
            2
        -k*x 
-2*k*x*e     
$$- 2 k x e^{- k x^{2}}$$
The second derivative [src]
                       2
    /          2\  -k*x 
2*k*\-1 + 2*k*x /*e     
$$2 k \left(2 k x^{2} - 1\right) e^{- k x^{2}}$$
The third derivative [src]
                         2
     2 /         2\  -k*x 
4*x*k *\3 - 2*k*x /*e     
$$4 k^{2} x \left(- 2 k x^{2} + 3\right) e^{- k x^{2}}$$
