Okay, so we're asked to fund medical serious for half and its release of convergence. So what is Thie McLaren's serious flap necks at axe? Because two zero at his fines. So this is just the constrictive at Max as euro over in pictorial and X minus zero to the power of end and of horses from zero to infinity. Okay, so which part in this for murder? And we shall fund that. This is on President Victoria over in Victoria. So this is Gilles. It gives us an plus one times X to power if in. And what is this? So this is a derivative of that's the power of plus one, the extra power from this one. The X and equals with Justo Extract out. This the fish is operator. So this is extra power plus one and his friend zeros for infinity and equals to the derivative of Earth. Next comes this part's actually power of n and A from zero to infinity. And this is our familiar. So it was two x or one minus x o. So our final answer is just to find the virility of this part. And this is just equal to woman's as to the power too womans at minus once, one times x. So it becomes too. One hour square of woman is X and okay fund the readers of Convergence. The rarest convergence is going to be the absolute events. The absolute bell of axe is less than one, so that is the greediest of convergence.
