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

    Hi. How can I integrate 1/(X^3 +1) ? Thank you to anyone who can help me :-) Write 1/(x^3 +1) as 1/[(x+1)(x^2-x+1)] Then use integration by parts, letting dv = dx/(x^2 -x +1) u = 1/(x+1) du = log (x+1) v = (2/sqrt3)arctan[(2x-1)/sqrt3]

    Integrate x dx/(1-x). I have proceeded thus- Int xdx/(1-x)=int -(x-1+1)/(x-1) =-Int[1+ 1/(x-1)]dx =-Int dx-Int dx/(x-1) =-x-log(x-1). On differentiating, we get original expression- d/dx[-x-log(x-1)]=-1-1/(x-1)=-x/(x-1)=x/(1-x). However, …
