We're starting with a limit as X goes to zero of one over X minus one over. Eat the X minus one. Um, so let's just go ahead and before doing anything else we write, this is a fraction. Okay, so here we just found common denominators in written in this a fraction. So now if we try to evaluate this limit, we see that we get zero on the top and we get zero on the bottom. So let's go ahead and use low Patel's rule reading LH for Low Patel's rule over the equals sign. And here in the numerator, where you take the derivative and we're going to get E to the X minus one, the dominator, we're going to have to do product room. So we have the derivative of X is one leaving us with E to the X minus one, and then we have X times e to the X, Okay. And trying to evaluate this woman, we see that we have 0/0. So we're actually going to have to do the Patel's role again. So the drone of the top is e to the X on the derivative bottom is e to the X plus e to the X plus X key to the X. And here this is a limit that we can evaluate. So on the top we get one Thebes nominator. We get one plus one plus zero LTD's one half.
