Comment (by nbruin):
Close as won't fix? `polar_plot` never gets its argument, since
`fibonacci` isn't symbolic:
{{{
sage: fibonacci(floor(tan((abs(alpha+pi/2)^0.22))))
TypeError: unable to convert x (=floor(tan(abs(1/2*pi +
alpha)^0.220000000000000))) to an integer
}}}
Apart from hobbling sage by equipping every conceivable function in sage
with a symbolic equivalent, we can't really do something about this
(perhaps document somewhere where newbies will look?)
