How do you integrate #int ln 2x^2 dx # using integration by parts? Calculus Techniques of Integration Integration by Parts 1 Answer Eddie Jul 12, 2016 reading this as : #int \ ln(2x^2) \ dx# then # = x ( ln2x^2 - 2) + C# Explanation: #int \ ln(2x^2) \ dx# using IBP #= int \d/dx(x) * ln2x^2 \ dx# # = x * ln2x^2 - int \ x * d/dx ( ln2x^2) \ dx# # = x ln2x^2 - int \ x * 1/(2x^2) 4x \ dx# # = x ln2x^2 - 2 int \ dx# # = x ln2x^2 - 2x + C# # = x ( ln2x^2 - 2) + C# Answer link Related questions How do I find the integral #int(x*ln(x))dx# ?
