Concavity and turning points

  1. May 17, 2010 #1
    1. The problem statement, all variables and given/known data
    need to find the turning points an concavity of this equation. y=(x^3)/(x^2-1),


    2. Relevant equations
    i know y'=(x^2(x^2-3))/((x^2-1)^2)
    and y''=(2x(x^2+3))/((x^2-1)^3)

    need to know the turning points and concavity
    3. The attempt at a solution

    Welcome to PF!

    Hi bruno87 ! Welcome to PF! :smile:

    (try using the X2 tag just above the Reply box :wink:)
    The turning points should be easy …

    what's the test for turning points? :smile:
