    For the first one, remember that
    derivatives

    e^x = e^xdx

    and
    e^x^2 = 2xe^x^2


    the second derivative from there
    f " (x) = 2 * e^x^2 * (2x^2 + 1) (chain rule)

    the chain rule is the PITA here

    f'(4) = plug in 4

    f"(4)=...plug in 4

    then use the derivatives to find the zeros, and use these as critical points; no given interval means the endpoints are infinity and negative infinity

    Let L be the length of the box, and let the girth equal the width AND the height of the rectangle (hence square ends)
    volume = V = L*w^2
    L + 4*w <= 114 inches


    because of this,


    L = 114 - 4*w
    V = (114 - 4*w)*w^2

    = 114*w^2 - 4*w^3, giving V as a function of only w.

    which is what you want; since optimization relates something to something else
    With the equation above, you can get dV/dW, since everything is now in terms of volume to width

    so you can derive that and see what you get for w/h

    you know how to derive, right?

    when deriving e^x

    the derivative is just e^x

    unless there are coefficients involved

    like the derivative of e^2x
    is
    2e^2x because of the chain rule

    so the derivative of e^x^2 (x^2= 2xdx) is
    2xe^x^2

    I'm pretty sure I did these same problems back in calc. That was like 5 years ago though.
