$$\cfrac \pi {1+\cfrac \pi {2+\cfrac \pi {3+\cfrac \pi {4+\cfrac {\pi} {\ddots}}}}}$$
I don't want a solution to this. I just want to know to begin ! I've been trying for almost an hour now. Thanks for the help
EDIT 1 :
Here is what I tried :
$f(n) = n + \frac {\pi} {f(n+1)}$
$f(n+1)(f(n)-n) = \pi$
$f(1)f(0)=\pi$
since, $\pi$ is the factor of two numbers. So one must be 1 and other must be $\pi.$
$f(2)(f(1)-1)=\pi$
If $f(1)=1$, then, $f(2)(1-1)=\pi$ which is impossible.
$So, f(0) = 1$ must be True!
Hence the answer is 1
Can someone please verify ? Thanks :)
