    btn_donateCC_LG_global.gif tbh ;) I have the answers at the ready.

    Maxima and minima occur where the slope is equal to zero, i.e., where the first derivative is equal to zero.

    It is a maximum if the second derivative is negative at the point and a minimum if the second derivative is positive at the point.
