Partial derivative

  1. Dec 5, 2009 #1
    1. The problem statement, all variables and given/known data

    Differentiate:

    [tex]y'''+ty''+y'+y'=0[/tex]

    2. Relevant equations



    3. The attempt at a solution

    I tried to use this definition:

    [tex](y')'=y''[/tex]

    I'd be thankful, if somebody could show me the rules of differentiating y'.

    You've got it. (y')'=y'', (y'')'=y'''. Etc. Don't forget to use the product rule on ty''.
