[00:00:00]So, we basically do is we have this function over here, x squared, right?

[00:00:04]So, here f of a that that is our one and our point a is equals to one. Okay, so we're simply going to replace it with 1 + h 1 f of 1. So, because we have to replace it with f of a and our f of a happens to be this is a and this is f of a. This happens to be one, okay? So, we simply have to replace it by one.

[00:00:34]And next we have an h, so limit as x approaches zero. So, now we basically have to every time we see an x here in inside the function, we need to replace it with 1 + h.
