Bugs item #708917, was opened at 20030324 12:34 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=708917&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: trigreduce(sin(x)^2/cos(x)^2) Initial Comment: trigreduce(sin(x)^2/cos(x)^2) => tan(x)^2 Shouldn't it return (1cos(2*x))/(1+cos(2*x))? For that matter, it would be nice if trigreduce(tan(x)^2) also did this, but the documentation of trigreduce explicitly says that it handles only sin's and cos's (unlike trigexpand, which handles trigs in general). On the other hand, Trigrat already does this.  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=708917&group_id=4933
