What is the second derivative of #f(x)=e^x + e^(-x / 2 #?
2 Answers
the first derivative by using the chain rule is
then take the derivative of that function
therefore,
again using the chain rule on the second element,
therefore the answer is
=
Explanation:
Since the second derivative is the derivative of the first derivative, we start by finding:
Re-writing:
We know
We need to use the Chain Rule for
We now differentiate this again:
Re-writing as before:
