∫3 at top and 2 at bottom
x/x^2+1 dx = ?


if you could show steps that would be great thanks

  • Calculus - ,

    actually theres an integral sign. at the top of the sign theres a 3. At the bottom of it, theres a 2.

  • Calculus - ,

    You can type it this way:

    ∫(x/(x^2 + 1)) dx for x= 2 to 3

    which is

    [ (1/2) ln (x^2 + 1) ] from 2 to 3
    = (1/2) ( ln 10 - ln 5)
    or
    (ln10 - ln5)/2
    or
    ln (10/5) / 2
    = (1/2) ln 2
