Question #7454e Calculus Graphing with the Second Derivative Notation for the Second Derivative 1 Answer Andrea S. Jul 19, 2017 #d^2/dx^2 (x^3logx) = x(6logx + 5)# Explanation: Using the product rule for the second order derivative: #d^2/dx^2 (x^3logx) = (d^2/dx^2 x^3)logx +2 (d/dx x^3)(d/dx logx) + x^3(d^2/dx^2 logx)# #d^2/dx^2 (x^3logx) = 6xlogx +2 xx 3x^2 xx 1/x + x^3(-1/x^2)# #d^2/dx^2 (x^3logx) = 6xlogx +6x -x# #d^2/dx^2 (x^3logx) = 6xlogx + 5x# #d^2/dx^2 (x^3logx) = x(6logx + 5)# Answer link Related questions What is notation for the Second Derivative?
