Bugs item #965926, was opened at 20040603 13:21 Message generated for change (Comment added) made by macrakis You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=965926&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: trigsimp exponentially slow on lists Initial Comment: trigsimp of a [] list can sometimes take time exponential in the length of the list. For example: trigsimp(makelist(sin(i)^2+cos(i)^2,i,1,N)) for N=4,5,... takes 0.12, 0.52, 1.50, 4.45, 13.97 secs. Also for sin(i)^2. Of course, it should take linear time. This doesn't happen  >Comment By: Stavros Macrakis (macrakis) Date: 20040603 13:22 Message: Logged In: YES user_id=588346 Oops, "this doesn't happen" should continue... in other cases, like sin(1)^2, sin(x)^2+cos(x)^2, etc.  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=965926&group_id=4933
