I want to make a simple plot for a talk. As an experiment I try plot(x^2,2,10) (*)
and it works as expected. So happily I go for the real thing plot(zeta(x),2,10) (**) Unfortunately I get a long list of exceptions but no clear indication what the problem is. plot(zeta,2,10) (*) yields an empty plot. plot(real(zeta(x)),2,10) gives again exceptions..... After several tries I finally find something that works plot(lambda x:real(zeta(x)),2,10) (**) In retrospect I can explain why this magic incantation makes sense. But I think many users will be baffled by the difference in complexity between (*) and (**). In Maple there is no difference between (*) and (**). This is sage 3.0.5. Released 2008-07-11.
