# Thread: find the second derivative

1. ## find the second derivative

I am begin the problem of finding the second derivative of $\displaystyle e^{-6x^2}$
To start off do I need to do something with logarithms?

If not
Outer fuction is $\displaystyle e^x$
Inner function is $\displaystyle -6x^2$

2. ## Re: find the second derivative

for $\displaystyle y= e^{f(x)} \implies y'= f'(x)\times e^{f(x)}$

Apply the product rule to this result to find the second derivative.
