| Jul 20, 2012 at 15:49 | comment | added | Malik Younsi | For information, $K(k)=EllipticK(k)$ in Maple. | |
| Jul 20, 2012 at 15:47 | comment | added | Malik Younsi | Yes, according to reference.wolfram.com/mathematica/ref/EllipticK.html. Weird... | |
| Jul 20, 2012 at 15:38 | comment | added | GH from MO | I clarified: K(k)=EllipticK[k^2] in Mathematica. | |
| Jul 20, 2012 at 15:20 | comment | added | GH from MO | Are you sure you typed in the function all right? In Mathematica I get a very different plot. For example, at k=4/5 it tells me K(3/5)=1.94957, K(4/5)=2.25721, so f(4/5)=0.8*2.25721*Sinh[(pi/2)*1.94957/2.25721]=3.27375, while your graph suggests a value below 3. | |

| Jul 19, 2012 at 19:50 | comment | added | Suvrit | I have a feeling that looking at Laplace transforms and Bernstein's theorem on completely monotonic functions along with some inverse Laplace transforms might help...but translating this feeling into a proof might be non-trivial... | |
