Hello, I am checking a book from Miroslav Lutovac for the nomen q(k)=e^(-pi * K'/K) of the elliptic functions. He gives for k=sin(86degrees) a q of 0.2954883855586914 on page 512. I did: q(k):= (%e)^(-%pi * elliptic_kc(1-k^2)/elliptic_kc(k^2)); q(sin(%pi * 86/180)),numer; And got: 0.2954883855586907 It is a very small difference - only in the last two digits, but is it significant for something wrong? Can anyone check this result? with friendly greetings, Peter |
