How do you find the second derivative of #y=ln((2x)/(x+3))# ? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions with Base e 1 Answer A. S. Adikesavan Nov 18, 2016 #1/(x+3)^2-1/x^2# Explanation: #y= ln 2 + ln x - ln (x|3)# #y'=0+1/x-1/(x+3)=x^(-1)-(x+2)^(-1)# #y''=(-1)x^(-1-1)-(-1)(x+2)^(-1-1)(x+3)'# #=-1/x^2+1/(x+3)^2(1)# Answer link Related questions What is the derivative of #f(x)=ln(g(x))# ?
