Comment #34 on issue 1766 by smichr: expand(power_base=True) is too
aggressive
http://code.google.com/p/sympy/issues/detail?id=1766
I get [-(4*log(7) + 5*LambertW(-7*2**(4/5)*6**(1/5)*log(7)/10))/(3*log(7))]
Yours is nicer in that it pulled a 2 form the 6 to make the 2**(4/5) become
2 and
cancel with the 10 in the denominator.
I just got done breaking apart commit 1766. I was able to find the cls(0.9)
and move
that. I'll work on the documentation for the ode helpers and change the
_gcdn to gcdn
later, etc...later this week. Maybe tomorrow.
All tests and doctests are passing here although I didn't check every
intermediate
commit after resorting. It's a 15 minute cycle here and I'm running out of
minutes
for tonight!
