We will use L'Hospital's Rule for the limit of x^sqrt(x) as x goes to 0+. Even though we will get a 0^0 when we plug in 0 into x^sqrt(x), 0^0 IS an indeterminate form so we must do more work in order to determine the limit. Here's an example of the limit with the indeterminate form 0^0 but we do not get 1. 👉 • a 0^0 limit that appro...

Poor L'Hopital. Because we think it's funny an entire generation of math enthusiasts are going to grow up believing his name is L'Hospital. And in a generation after that his original name will be lost to time.

He actually made a mistake. There's no 's' in L'Hopital. I guess I can give him a break though. He wasn't around in the 1600's :-)

Well, actually in older French spelling his name was spelled L'Hospital, which is why it's written today in modern French with an o circumflex: L'Hôpital. Source: Math major currently speaking French at A1 level so I can understand fundamental math treatises. 😀

Before watching the video: Find the lim(x→0+) x↑(x↑½) Consider x↑(x↑½) as exp((x↑½)(lnx)) lim(x→0+) exp((x↑½)(lnx)) as exponential function is continuous over the target domain, limit of the exponential function of a function of x is the same as the exponential function of the limit of that function of x. thus lim(x→0+) exp((x↑½)(lnx)) = exp(lim(x→0+) ((x↑½)(lnx))) Defining L = lim(x→0+) ((x↑½)(lnx)): The question now reduces to: Find exp(L). L = lim(x→0+) ((x↑½)(lnx)) This is of the indeterminate form 0·(-∞) Rewriting to obtain a more workable indeterminate form, L = lim(x→0+) ((lnx)/(x↑(-½))), which is of the indeterminate form (-∞)/∞, allowing for the use of L'Hospital's Rule. L = lim(x→0+) (d/dx (lnx)/d/dx (x↑(-½))), = lim(x→0+) ((x↑(-1)/((-½)(x↑(-3/2)))) = lim(x→0+) (-2√x) = 0 L = 0. exp(L) = exp(0) = 1. Thus, lim(x→0+) x↑(x↑½) = exp(L) = 1.

Why do americans love this "L'hopitals rule"? Just use the "growth comparison" (that's how it's named in french), α^x is dominant over x^α which is dominant over ln(x), with "α" a constant

If you know that xln(x) when x approches 0 is 0, you can write sqrt (x) * ln(x) as 2(sqrt(x)*ln(sqrt (x))= 2*0=0=L because sqrt (x) approches 0 when x approches 0, so do it sqrt (x)*ln(sqrt(x))
