How do you find the derivative of #e^((x^2)/2)#? Calculus Basic Differentiation Rules Chain Rule 1 Answer NJ Mar 14, 2018 #f'(x) = xe^(x^2/2)# Explanation: #f(x) = e^(x^2/2)# We need to use the chain rule: #f'(x) = (d(e^(x^2/2)))/(d(x^2/2)) * (d(x^2/2))/(dx)# #f'(x) = e^(x^2/2) * ((2x)/2)# #f'(x) = xe^(x^2/2)# Answer link Related questions What is the Chain Rule for derivatives?
