Hello,
It's been 20 years since I did any calculus, so please be gentle. :)
Using SymPy 0.7.2 and IronPython 2.7.4.
import sympy
from sympy import *
# calculate arc length
x = symbol('x')
d = diff(2 * pow(x, 2), x)
print d
length = integrate(sqrt(1 + pow(d, 2)), (x, 5, 10))
print length
This outputs '4*x' as expected then 'zip() argument after * must be a
sequence, not dictionary-itemiterator'.
I believe the integration is solvable to 75.173 [1], so I assume I have an
error in my Python and/or SymPy syntax. Can anyone please give me some
pointers? Thanks!
