[sage-devel] problems with Bessel functions

2009-12-08 Thread Pablo De Napoli
Hi I'm trying to do some computations with Bessel functions using Sage. Unfortunately, they don't seem to behave like other functions. For example: to get the plot of the sine function over the interval (0,100) plot(sin(x),(x,0,100)) works. However, plot(bessel_J(0,x),(x,0,100)) does not. Giv
