    Concave up concave down

    Need to find the intervals in which the equation is concave up as well as concave down, the pionts of inflection and critical points

    heres the equation

    f(t) = sin2(t) 0 ≤ tπ

    Thanks

    Did you mean sin^2(t) or sin(2t)?

    This is a pretty straightforward application of definitions, you'll need to find the first and second derivatives and set them to zero, then divide the interval [0, π] accordingly.
