There are some significant upgrades to the trigsimp routine that are available from
https://github.com/sympy/sympy/pull/772 Here is the pull request message: Although a new trigsimp routine has been discussed, these modifications may fill (more of) the gap until then. 6 new patterns have been added; factoring and rewriting are used when necessary; 7 issues are dealt with in the process. The test suite gets 4 seconds longer because of the new tests (one that used to hang now solves in 3 seconds) and an additional 5 seconds (1%) is added to the test suite runtime because of the more thorough processing (it's always recursive now). Various permutations of processing increased the suite time by 2 minutes and required over 10 seconds to solve the ode that used to hang, so the current code of this request seems to be a good trade-off: a slightly longer run time but more of what you expect from trigsimp. -- You received this message because you are subscribed to the Google Groups "sympy" group.
