integrate 1/x dx w.r.t x
answer should be log(x) or ln(x)
and why

  • maths-urgently needed -

    because d/dx log(x) = 1/x,

    ∫dx/x = log(x)+C

    is that why enough, or is there yet something missing?

    And, maybe you haven't seen the old chestnut

    ∫d(cabin)/cabin = log cabin + C = houseboat
