can anyone explain this:
from approximation one know's that the legendre coefficients converge exponentially to zero and not to infinity!
and indeed with mpmath I get a better answer:
Is there an overhead happening, when I numerically evaluate large rationals or something???
Thanks in advance, maldun
If you look at the output of
you'll see that it is a massive expression with large rationals, powers of pi, etc. If
For example, the lines
tell you that if evaluate the expression using 500 bits of precision, it's definitely 0.000000... (at least 53 zeros). Internally, this is done by evaluating with 500 bits of precision and rounding down and also evaluating with 500 bits and rounding up, and tracking the resulting "interval".
