And here's a strange and perhaps related result. A tests that gave a False at one point gives a True later:
C:\Documents and Settings\chris>\python26\python.exe Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from sympy import * >>> from sympy.abc import * >>> separatevars(y / pi * exp(-(z - x) / cos(n))) y*exp((x - z)/cos(n))/pi >>> separatevars(y / pi * exp(-(z - x) / cos(n))) == y*exp((x - z)/cos(n))/pi False OK, there was the False...now be patient... >>> ans = separatevars(y / pi * exp(-(z - x) / cos(n))) >>> ans == y*exp((x - z)/cos(n))/pi True It's True if the result is assigned to a variable, but keep watching.... >>> separatevars(y / pi * exp(-(z - x) / cos(n))) y*exp((x - z)/cos(n))/pi >>> type(separatevars(y / pi * exp(-(z - x) / cos(n)))) <class 'sympy.core.mul.Mul'> >>> (separatevars(y / pi * exp(-(z - x) / cos(n)))) == y*exp((x - z)/cos(n))/pi False It' still False but.... >>> repr(separatevars(y / pi * exp(-(z - x) / cos(n)))) 'y*exp((x - z)/cos(n))/pi' >>> repr(y*exp((x - z)/cos(n))/pi) 'y*exp((x - z)/cos(n))/pi' >>> separatevars(y / pi * exp(-(z - x) / cos(n))) y*exp((x - z)/cos(n))/pi >>> separatevars(y / pi * exp(-(z - x) / cos(n))) == y*exp((x - z)/cos(n))/pi True >>> NOW IT'S TRUE!? Are the first occurance and this one the same: A)separatevars(y / pi * exp(-(z - x) / cos(n))) == y*exp((x - z)/cos (n))/pi B)separatevars(y / pi * exp(-(z - x) / cos(n))) == y*exp((x - z)/cos (n))/pi Yes...why are they True for the latter occurance but not for the first? -- You received this message because you are subscribed to the Google Groups "sympy-patches" group.
