    Hi, I think this is a relatively simply question to answer but my brain's on the fritz, could anyone tell me when you integrate both sides of an equation are they always equal. Im thinking for this kind of thing:

    dv = Ud(ln m) + gdt

    where U and g are constants.

    So is both sides of the eq. still equal if I integrate the left by dv and the expressions on the right by d(ln m) and dt respectively?

    Yes, but remember the constant of integration.

    dv/dt = U (d/dt)(ln m) + g
    v = U(ln m) + gt + c
