n+1 = 1 2 x n + a x n : The intuition is very simple: if x n is too big (> p a), then a=x n will be too small (< p a), and so their arithmetic mean x n+1 will be closer to p a. It turns out that this algorithm is very old, dating at least to the ancient Babylonians circa 1000 BCE.1 In modern times, this was seen to

[PDF File]Integral of square root of (1-cos x)dx
https://info.5y1.org/sqrt-2-cosx-1_1_1336b1.html
Integral of square root of (1-cos x)dx I've been wondering about the following integral recently: $$ I = \int\sqrt{1+\cos x}\,\text{d}x $$ The way I integrated it is I used the identity $\sqrt{1+\cos x} = \sqrt2\cos\frac x2$, and so $$ I = 2\sqrt2\sin\frac x2 + C $$ the problem is that $\sqrt{1+\cos x}$ is actually integrable over the entire real line, but the derivative of $2\sqrt2\sin\frac ...

this : \(\displaystyle \int\sqrt{1+y'^2}dx\) and if we put cosx instead of y' we have the above integral. \(\displaystyle \int\sqrt{1+cos^2x}dx\)(Nerd) Well, as you can see, it can't be done using a finite number of elementary functions.
