I have worked with bessel functions before and haven't had a problem
until now.
Code:
-----
r,p,z,ro,gro,g,k = var('r, p, z,ro,gro,g,k')
g = 1; k = 1; ro = 1; gro = 1
def Psi(r,z): return lambda r,z: (r*bessel_J(1, g*r))/(ro*bessel_J(1,
gro))*cos(k*z) if y != 0 and t != 0 else infinity
Error:
-----
Syntax Error
