    Handling a constant

    dx/x=v^3dv/v^4+1
    After integration you get \log x=(\log (v^4+1)/4)+c
    I think this yields 4\log x=\log (v^4+1)+4c
    Thus \log x^4= \log (v^4+1)+4c
    I don't know how to handle the constant. Help?

    You have...

    \ln x^{4} = \ln (1+v^{4}) + 4\ c (1)

    ... that setting 4\ c = \ln \alpha^{4} and 'exponentiating' becomes...

    x = \alpha\ (1+v^{4})^{\frac{1}{4}} (2)

    Kind regards
