@DanielFischer does that mean its possible to have an empty basis?

comment Am I doing integration correctly? Wolfram alpha has a different answer
@MichaelHardy for example in this problem wolframalpha.com/input/…^2%2Blnx%29 I get ln|(lnx)^2+lnx|+C the solution there looks entirely different with no alternative forms i try getting the derivative of both solutions but both of them still look different

comment Am I doing integration correctly? Wolfram alpha has a different answer
@Integrator is there an easy way to find out whether the two solutions are both correct? would having the same x value and checking for equality be enough?

comment Am I doing integration correctly? Wolfram alpha has a different answer
@MichaelHardy like one of the answers below when I double check my answers most of the time computation engines give a different form of the answer, Im having a hard time telling whether my answer is really equivalent or if it is truly wrong. Is there an easy way to find out if they are both the correct answer?

comment Am I doing integration correctly? Wolfram alpha has a different answer
@MichaelHardy how can I check if the two result of integration are equal without transforming one into the other? Will simply inputing the same value for their variables and checking for equality be enough? thanks in advance
