hello i need help for derivate this function: x+1+1/(x+2)

thanks for your help

  • math -

    Go on: wolframalpha dot com

    When page be open in rectangle type:

    derivative x+1+1/(x+2)

    and click option =

    After few seconds when you see result click option:

    Show steps

  • math -

    let y = x +1 + 1/(x+2)
    = x + 1 + (x+2)^-1

    dy/dx= 1 - (x+2)^-2
    or
    = 1 - 1/(x+2)^2
