...-^ , °i If the expression just given between brackets vanishes at any point we have at that point P Now x — - is the abscissa of the point of intersection of the tangent to the curve at the point (#, y) and the axis of x ; we will put f for this abscissa. We assume that y is positive and that the... | |
