2nd Order ODE

  1. Sep 23, 2008 #1
    Hey guys,

    1. The problem statement, all variables and given/known data
    Solve the following DE,

    y"+t(y')^2=0


    I'm not sure what to do with the square there. Would it help if i divided the whole equation by y'?

    Thanks

    Hey 2RIP! :smile:

    HInt: put y' = v …

    then it's v' + tv2 = 0. :wink:

    Oh thanks tiny-tim, it becomes a separable equation :P
